I have a simple problem. I want to update my classes inside my inputs on form submit.
<div class="form-group">
<input class="form-control" ng-class="{'has-error': signup.$submitted && signup.name.$invalid}" type="text" name="name" ng-model="formData.name" required minlength="2" placeholder="Full Name">
</div>
Here's my app.js:
spinnrApp.controller('FormController', ['$scope', '$http', '$state', function (scope, http, state){
// get list of cities and store it to select
http.get('cities.json').success(function(data){
scope.cities = data;
})
// we will store all our form data in this object
scope.formData = {};
// function to process the form
scope.processForm = function(isValid) {
scope.$submitted = true;
if(isValid && state.$current=='registration.spinnrapp') {
state.go('registration.artist');
} else if(isValid && state.$current=='registration.artist') {
state.go('registration.share');
} else if(!isValid && state.$current=='registration.artist') {
alert('Please make sure you have selected an artist.');
} else if(!isValid && state.$current=='registration.spinnrapp') {
return;
}
};
}]);
When I execute my submit via ng-click calling this function, my signup.$submitted still stays as false. I also have a reference from this Plunker: http://plnkr.co/edit/xDIzC0A50cXxMpIHeP3C?p=preview
That Plunkr updates its class. Why isn't mine doing the same? Am I doing something wrong?

This Meteor client code is expected to show a progress bar animation when a button is clicked. The problem is that the progress element is null when the animation code tries to use it.
How can it be fixed? thx
Template.registerHelper('session', (value) => {
return Session.get(value);
})
Template.footer.events({
'click button[data-action=carSearch]': function (e) {
e.preventDefault();
clickInfo();
}
});
'clickInfo': function () {
Session.set('inProgress', true); // makes the element visiable
progressBarStart(); // start the animation
}
'progressBarStart': function () {
let bar = document.getElementById('bar'); //<-- bar is always null
if (bar.value < 70) {
setTimeout(lib.progressBarStart(), 1000); controls the speed
bar.value += 1;
}
}
<template name="nameSearch">
<div id="nameSearch">
<p id="result" data-id={{_id}}>
{{{display.result}}} <br>
{{#if (session 'inProgress')}}
<progress id="bar" value="0" max="70"></progress>
{{/if}}
</p>
</div>
</template>
You should give the render a time to re-render after calling Session.set('inProgress', true);, 50ms will be enough.
Next, you should declare clickInfo and progressBarStart correctly, not like you have them now.
function clickInfo() {
Session.set('inProgress', true);
Meteor.setTimeout(progressBarStart, 50);
}
function progressBarStart() {
...
}
I'd also recommend to use dedicated helper to obtain inProgress status:
Template.footer.helpers({
isInProgress: function() {
return Session.equal('inProgress', true);
}
});
And use it in your template:
{{#if isInProgress}
...
{{/if}}
You must not use Session variables for such a small reason. Meteor JS has given a facility to use Reactive Variables at template level manipulations.
You should give the render a time to re-render after calling Template.instance().inProgress.set(true);.
I'd also recommend to use dedicated helper to obtain inProgress status:
Template.footer.onCreated(function(){
this.inProgress = new ReactiveVar(false);
});
Template.footer.helpers({
isInProgress: function() {
return Template.instance().inProgress.get();
}
});
And use it in your template:
{{#if isInProgress}
...
{{/if}}
I'm learning how to use meteor with react so forgive the basic question.
I want to create a form that populates when the page loads if the data has already been submitted. I've been trying to use getInitialState however I'm not getting anywhere. Some help would be really appreciated.
Path: MyResolutions.jsx
export default class MyResolutions extends Component {
getInitialState() {
return {
resolution: Resolutions.find().fetch(),
timeToComplete: Resolutions.find().fetch(),
};
}
render() {
return (
<form onSubmit={this.addResolutions.bind(this)}>
<input
type="text"
ref="resolution"
placeholder="Resolution title"
value={this.state.resolution} />
<input
type="text"
ref="timeToComplete"
placeholder="Time To Complete"
value={this.state.timeToComplete} />
<button type="submit">Submit</button>
</form>
)
}
}
This depends on the shape of your data coming from your initial state:
getInitialState() {
return {
resolution: Resolutions.find().fetch(),
timeToComplete: Resolutions.find().fetch(),
};
}
Assuming that this.state.resolution returns something like:
{
value: 'some string'
}
You would actually have to do something like this.state.resolution.value . So maybe try console.log(this.state.resolution) to get the shape of your data and then use dot notation to display the keys you need.
I'm using Meteor with React. I have a really simple goal, but i have tried a lot and can't solve it for myself. I will show you my attemps below.
I want to create a form for the Ingredients. At the first moment there is only one input (for only one ingredient) and 2 buttons: Add Ingredient and Submit.
class IngredientForm extends Component {
render() {
return(
<form onSubmit={this.handleSubmit.bind(this)}>
<input type="text"/>
{ this.renderOtherInputs() }
<input type="button" value="Add Ingredient" onClick={this.addIngredient.bind(this)}>
<input type="submit" value="Submit Form">
</form>
);
}
}
So when I click Submit then all the data goes to the collection. When I click Add Ingredient then the another text input appears (in the place where renderOtherInputs() ).
I know, that Meteor is reactive - so no need to render something directly. I should underlie on the reactive data storage.
And I know from the tutorials the only one way to render something - I should have an array (that was based on collection, which is always reactive) and then render something for each element of that array.
So I should have an array with number of elements = number of additional inputs. that is local, so I can't use Collection, let's use Reactive Var instead of it.
numOfIngredients = new ReactiveVar([]);
And when I click Add button - the new element should be pushed to this array:
addIngredient(e) {
e.preventDefault();
let newNumOfIngredients = numOfIngredients.get();
newNumOfIngredients.push('lalal');
numOfIngredients.set(newNumOfIngredients);
}
And after all I should render additional inputs (on the assumption of how many elements I have in the array):
renderOtherInputs() {
return numOfIngredients.get().map((elem) => {
return(
<input type="text"/>
);
}
}
The idea is: when I click Add button then new element is pushed to the ReactiveVar (newNumOfIngredients). In the html code I call this.renderOtherInputs(), which return html for the as many inputs as elements I have in my ReactiveVar (newNumOfIngredients). newNumOfIngredients is a reactive storage of data - so when I push element to it, all things that depends on it should re-render. I have no idea why that is not working and how to do this.
Thank you for your help.
Finally I got the solution. But why you guys don't help newbie in web? It is really simple question for experienced developers. I read that meteor and especially react have powerful communities, but...
the answer is: we should use state!
first let's define our state object in the constructor of react component:
constructor(props) {
super(props);
this.state = {
inputs: [],
}
}
then we need a function to render inputs underlying our state.inputs:
renderOtherInputs() {
return this.state.inputs.map( (each, index) => {
return (
<input key={ index } type="text" />
);
});
}
and to add an input:
addInput(e) {
e.preventDefault();
var temp = this.state.inputs;
temp.push('no matter');
this.setState({
inputs: temp,
});
}
p.s. and to delete each input:
deleteIngredient(e) {
e.preventDefault();
let index = e.target.getAttribute('id');
let temp = this.state.inputs;
delete temp[index];
this.setState({
inputs: temp,
});
}
In my autoform the value of a field is the difference of two other input fields. It is not allowed to be updated by the user. Unfortuantly at the moment it is not possible to set a single field to readonly in a form. So my approach is to create an autoValue and a custom Validation to prevent an update
My code so far:
'SiteA.Settings.RXSignalODU1difference': {
type: Number,
label: "RX Signal [dBm] ODU1 difference (without ATPC +/- 3dbm)",
decimal: true,
autoform: {
type: "number"
},
autoValue: function() {
var ODU1gemessen = this.field("SiteA.Settings.RXSignalODU1");
var ODU1planned = this.field("SiteA.Settings.RXSignalODU1planned");
if (ODU1gemessen.isSet || ODU1planned.isSet) {
return ODU1gemessen.value - ODU1planned.value;
}
},
custom: function() {
var ODU1gemessen = this.field("SiteA.Settings.RXSignalODU1");
var ODU1planned = this.field("SiteA.Settings.RXSignalODU1planned");
var dif = ODU1gemessen.value - ODU1planned.value;
if (this.value !== dif) {
return "noUpdateAllowed";
}
}
},
My Simple.Schema message:
SimpleSchema.messages({noUpdateAllowed: "Can't be updated"});
Unfortunatly no message pops up.
EDIT
This method will create a disabled input box within your form that will automatically show the difference between two other input fields as the user types.
First, we define session variables for the values used in the calculation and initialize them to undefined.
Template.xyz.onRendered({
Session.set("ODU1gemessen", undefined);
Session.set("ODU1planned", undefined);
});
Then we define two events, that will automatically update these session variables as the user types.
Template.xyz.events({
'keyup #RXSignalODU1' : function (event) {
var value = $(event.target).val();
Session.set("ODU1gemessen", value);
},
'keyup #RXSignalODU1planned' : function (event) {
var value = $(event.target).val();
Session.set("ODU1planned", value);
}
});
Then we define a helper to calculate the difference.
Template.xyz.helpers({
RXSignalODU1difference : function () {
var ODU1gemessen = Session.get("ODU1gemessen");
var ODU1planned = Session.get("ODU1planned");
if (!!ODU1gemessen || !!ODU1planned) {
return ODU1gemessen - ODU1planned;
}
}
});
My HTML markup looks like this. Note, to still control the order of the form, I use a {{#autoform}} with a series of {{> afQuickfields }} rather than using {{> quickForm}}.
To display the calculated difference, I just create a custom div with a disabled text box.
<template name="xyz">
{{#autoForm collection="yourCollection" id="yourId" type="insert"}}
<fieldset>
<legend>Enter legend text</legend>
{{> afQuickField name="SiteA.Settings.RXSignalODU1" id="RXSignalODU1"}}
{{> afQuickField name="SiteA.Settings.RXSignalODU1planned" id="RXSignalODU1planned"}}
<div class="form-group">
<label class="control-label">RXSignalODU1difference</label>
<input class="form-control" type="text" name="RXSignalODU1difference" disabled value="{{RXSignalODU1difference}}">
<span class="help-block"></span>
</div>
</fieldset>
<button class="btn btn-primary" type="submit">Insert</button>
{{/autoForm}}
</template>
Original Answer - not recommended
If you are generating your form as a quickForm, you could do something like
{{>quickForm collection='yourCollection' omitFields='SiteA.Settings.RXSignalODU1difference'}}
This will leave this field off the form, so the user won't be able to update it.
If you still want to display the value somewhere along with the form as the user types in the other two values, you could define a helper in your client side js
something like
Template.yourFormPage.helpers({
diff: function () {
var ODU1gemessen = $('[name=SiteA.Settings.RXSignalODU1]').val();
var ODU1planned = $('[name=SiteA.Settings.RXSignalODU1planned]').val();
if (!!ODU1gemessen || !!ODU1planned) {
return ODU1gemessen - ODU1planned;
}
}
});
You'll want to double check how the field names are being rendered in your DOM. Autoform assigns the name attribute using the field names in your schema, but I don't know how it handles nested keys... (i.e. whether it names the element 'SiteA.Settings.RXSignalODU1' or just 'RXSignalODU1' )
And then just display the value somewhere in your html as :
{{diff}}
I have this form where the user can insert a quantity in an input field, and see the total in another input field. It works when you insert the numbers manually and I want it to work with buttons too, but i just can't get it to work.
Here's the code:
HTML
<form id="buyForm" method="post" action="cart.php">
<label>Choose quantity</label>
<div>
(+)increase
<input type="text" id="qty1" name="qty[]"/>
(-)decrease
</div>
<input type="text" id="cost1" value="50" style="display:none; visibility:hidden;" name="cost[]" />
<input type="text" id="price1" name="price[]" />
</form>
Js
// Calculate
function calc(idx) {
var price = parseFloat(document.getElementById("cost"+idx).value)*
parseFloat(document.getElementById("qty"+idx).value);
// alert(idx+":"+price);
document.getElementById("price"+idx).value= isNaN(price)?"0.00":price.toFixed(2);
}
window.onload=function() {
document.getElementsByName("qty[]")[0].onkeyup=function() {calc(1)};
document.getElementsByName("cost[]")[0].onkeyup=function() {calc(1)};
}
//Increase/decrease buttons
$(function() {
$(".button").click(function() {
var $button = $(this);
var oldValue = $button.parent().find("input").val();
if ($button.text() == "+") {
var newVal = parseFloat(oldValue) + 1;
// AJAX save would go here
} else {
// Don't allow decrementing below zero
if (oldValue >= 1) {
var newVal = parseFloat(oldValue) - 1;
// AJAX save would go here
}
}
$button.parent().find("input").val(newVal);
});
});
Here it is as jsfiddle: http://jsfiddle.net/rcheH/5/
Can someone please help me with this?
Thanks in advance!
