So I am emitting data collected from a form. All Q-Input functions are triggered just fine with #change, however, nothing is happening with any of the Q-Select elements:
<q-input
rounded
standout
bg-color="grey-3"
type="text"
v-model="nombreVehiculo"
placeholder="Nombre del modelo"
class="input inputPosition q-mb-md"
#change="emittedNombreVehiculo"
/>
<span class="text-black inputLabel">Año</span>
<q-input
rounded
standout
bg-color="grey-3"
type="text"
v-model="fecha"
placeholder="(2008, 2009, 2010)"
class="input inputPosition q-mb-md"
#change="emittedFecha"
/>
<span class="text-black inputLabel">Transmisión</span>
<q-select
rounded
standout
bg-color="grey-3"
type="text"
v-model="transmision"
placeholder="(2008, 2009, 2010)"
class="input inputPosition q-mb-md"
:options="opcionesTransmision"
#change="emittedTransmision"
/>
<script>
const opcionesTransmision = ["manual", "automático"];
function emittedTransmision(value) {
emit("emit:transmision", transmision.value);
console.log(transmision.value);
}
</script>
Any pointers would be greatly appreciated. As I mentioned above, I have attempted using #input but it still does nothing, the function will just not trigger at all.
Use #update:model-value="emittedTransmision"

I have an angular 7 reactive form, input field in this form is to let user see and modify time and then using Save() save it back to our db, the problem is that user can enter any none sense numbers in this field which dose not make sense in terms of Time.(like hours should be 1-24, Minutes 1-60)
My question is how can I validate what user entered into time field and if its valid then let Save btn be active?
Note: Based on my testing even though its none sense time entry but while trying to save its not saving to db and its probably sql not letting that happen.
I googled but i could not find anything, also angular has only email Validators which u can put while defining form.
this is my form defination
timeForm: FormGroup = new FormGroup({
Id: new FormControl(''),
Time: new FormControl(''),
});
and this is my HTML side
<form style="background-color: aliceblue;" [formGroup]="service.timeForm">
<mat-grid-list cols="1" rowHeight="120px">
<mat-grid-tile>
<div class="form-controles-container">
<input type="hidden" formControlName="Id" />
<mat-form-field>
<input formControlName="Time" matInput placeholder="Time" />
</mat-form-field>
<div class="button-row">
<button mat-raised-button color="primary" type="submit" (click)="Save()">Save</button>
<button mat-raised-button color="warn" (click)="Cancel()">Cancel</button>
</div>
</div>
</mat-grid-tile>
</mat-grid-list>
</form>
I need some sort of validation when user punch in any input which dose not make sense in Time my Save btn should not be activated.
I appreciate your help and guideline.
You can use the HTML type="time" or if you want more you can simply use a library like: JsDaddy/ngx-mask found on Github. Use it like this:
HTML with MatInput:
<input formControlName="Time" matInput placeholder="Time" type="time" />
With ngx-mas:
<input formControlName="Time" matInput placeholder="Time" mask="Hh:m0" />
Adding type="time" in all input time type use cases always help.
I have this html:
<div class="entry-content">
<div class="job_listings" data-location="" data-
keywords="" data-show_filters="true" data-
show_pagination="false" data-per_page="10" data-
orderby="featured" data-order="DESC" data-categories=""
>
<form class="job_filters">
<div class="search_jobs">
<div class="search_keywords">
<label for="search_keywords">Keywords</label>
<input type="text" name="search_keywords"
id="search_keywords" placeholder="Keywords" value=""
/>
</div>
<div class="search_location">
<label for="search_location">Location</label>
<input type="text" name="search_location"
id="search_location" placeholder="Location" value="" />
</div>
I want to place the label Where? before location and What? before keywords using css.
Tried:
label[What?]:before {
content: "search_location";
color: green;
}
Didn't work.
At the moment the label location listed in my html shows up as a placeholder, not a label- likewise for the label search keywords This is fine but i would like those placeholders replacing with, for location London, Berlin, Bristol... and for search keywords Chef, Cleaner, Manager...
It's perhaps clearer if you view at: https://adsler.co.uk/jobs/
Couldn't you just place the label with html? Like this
<div class="entry-content">
<div class="job_listings" data-location="" data-
keywords="" data-show_filters="true" data-
show_pagination="false" data-per_page="10" data-
orderby="featured" data-order="DESC" data-categories=""
>
<form class="job_filters">
<div class="search_jobs">
<div class="search_keywords">
<label style="color: green;">What?</label>
<label for="search_keywords">Keywords</label>
<input type="text" name="search_keywords"
id="search_keywords" placeholder="Keywords" value=""
/>
</div>
<div class="search_location">
<label style="color: green;">Where?</label>
<label for="search_location">Location</label>
<input type="text" name="search_location"
id="search_location" placeholder="Location" value="" />
</div>
Based on the HTML snippet you've provided, your CSS selector label[What?]:before is not going to resolve to anything. Square brackets [] are used to select elements based on one of their attributes (see attribute selector definition). You appear to be trying to pass in a desired value (which doesn't exist yet) as an attribute selector, which is impossible.
Looking at the site, the other trouble you're having is that the labels themselves have been hidden. This is currently in your CSS, so will need to be changed or otherwise overridden:
.job_filters .search_jobs div label {
display: none;
}
Then, as already suggested by Mr Lister, something like this will get you on the right track. I've tested in the browser on your site and it works once the labels have been unhidden:
label[for="search_location"]:before {
content: "Where?";
}
label[for="search_keywords"]:before {
content: "What?";
}
I'm going to assume that your actual intention is for the labels to display but you want to change their existing values from "Keywords" and "Location" using only CSS? It's not achievable. You could use a bit of JavaScript to change the text content, but not by CSS with your current implementation.
Is there any way to have a slider and next to it an editable field with it's current value?
I am using MDL and not polymer, because its light weight and should be distributed with locally run software.
This is a way:
<input class="mdl-slider mdl-js-slider" type="range"
min="0" max="100" value="50" tabindex="0" id = "slide_01">
<form action="#">
<div class="mdl-textfield mdl-js-textfield" id="text_01">
<input class="mdl-textfield__input" type="text" >
</div>
</form>
and
$('#slide_01').on('input',function(){
$("#text_01").get(0).MaterialTextfield.change(this.value);
});
$('#inp_text_01').keyup(function() {
$("#slide_01").get(0).MaterialSlider.change($('#inp_text_01').val());
});
-- updated the code and the fiddle to make it update the slider when the value is entered in the field --
https://jsfiddle.net/n6xy84ov/
I think there should be a better way, referring to my question here:Fetching the value of a mdl-textfield
I'm trying to load a form with an object that has a enum property, seems that everything is working correctly, but when I try to apply a class I get an error. I can see in the HTML code that checked property is been apply correctly, however I need to apply an specific class to the checked element and in the following line is the one that I have the problem.
th:classappend="${'__${currency}__' == '__${reference.currency}__' ? 'active'}"
The complete element looks like this
<div class="btn-group" data-toggle="buttons">
<label th:each="currency : ${T(entity.CurrencyEnum).values()}"
th:for="${#ids.next('currency')}" class="btn btn-default" th:classappend="${'__${currency}__' == '__${reference.currency}__' ? 'active'}">
<input type="radio" th:name="currency" th:field="*{currency}"
th:text="${currency}" th:value="${currency}" />
</label>
</div>
Thanks in advance...
--- UPDATE ---
Here is a sample code after solving the issue. The problem was where I place the final } please be carefull with this detail.
<div th:fragment="currency (selected)">
<label
th:each="currency : ${T(CurrencyEnum).values()}"
th:for="${#ids.next('currency')}" class="btn btn-default"
th:classappend="${currency == selected} ? 'active'"> <input type="radio"
th:name="currency" th:field="*{currency}" th:text="${currency}" th:value="${currency}" />
</label>
</div>
Assuming that reference is a variable defined somewhere and it is visible in this contex, you can try with this:
th:classappend="${currency} eq ${reference.currency} ? 'active'"
I want to create a small count button but don't know how to make it in JavaScript...
Here's the code :
HTML
<div id="input_div">
<input type="text" size="25" value="0" id="count">
<input type="button" value="-" id="moins">
<input type="button" value="+" id="plus">
</div>
It must increase AND decrease the number in the input[type=text] when click on the -/+ button.
Can someone help me ?
You'd need two things.
Variables - which are the way to store information in JavaScript
Event handlers, which are the way to react to events in JavaScript
First, let's create a script tag, and put a JavaScript count variable in it, we'll put it in the bottom of our body tag:
<script>
var count = 0;
</script>
Now, we want to create a handler, that is something that executes whenever the plus and minus signs are clicked
<script>
var count = 0;
function plus(){
count++;
}
function minus(){
count--;
}
</script>
We've created two functions to call when the buttons are clicked, but we do not update the value in the HTML, or call them yet, let's update the value in the HTML.
We'll do so by document.getElementByID for the element to update and then change its value. Our script tag should look something liks this:
<script>
var count = 0;
var countEl = document.getElementById("count");
function plus(){
count++;
countEl.value = count;
}
function minus(){
count--;
countEl.value = count;
}
</script>
One last thing, we need to tell the elements in the DOM to execute those handlers.
<div id="input_div">
<input type="text" size="25" value="0" id="count">
<input type="button" value="-" id="moins" onclick="minus()">
<input type="button" value="+" id="plus" onclick="plus()">
</div>
We've added them as event handlers to the DOM reacting to a click on the buttons, completing the task.
Now, here are some things we can improve:
We can use addEventListener to avoid polluting our DOM, and create unobtrusive JavaScript.
We can use a more advanced tool like KnockoutJS to handle binding the value we have to the DOM element instead of updating it ourselves.
We can read Eloquent JavaScript and learn more about how the language works!
Good luck, happy JavaScripting, and happy learning :)
DEMO FIDDLE FOR JAVASCRIPT
code html -
<div id="input_div">
<input type="text" size="25" value="0" id="count" />
<input type="button" value="-" id="minus" onClick = "doMinus();" />
<input type="button" value="+" id="plus" onClick = "doPlus();" />
</div>
code javaScript -
function doMinus(){
document.getElementById("count").value = --document.getElementById("count").value;
}
function doPlus(){
document.getElementById("count").value = ++document.getElementById("count").value;
}
jQuery Version
DEMO FIDDLE FOR JQUERY
code html -
<div id="input_div">
<input type="text" size="25" value="0" id="count" />
<input type="button" value="-" id="minus" />
<input type="button" value="+" id="plus" />
</div>
code jQuery -
$('#minus').click(function(){
$("#count").val(parseInt($("#count").val())-1);
});
$('#plus').click(function(){
$("#count").val(parseInt($("#count").val())+1);
});
U can write some script as shown
<script>
function increase(){
var a = 1;
var textBox = document.getElementById("count");
textBox.value = a;
a++;
}
</script>
<body>
<button type="button" onclick="increase()">+</button>
<input type="text" id="text">
</body>
similarly u can do it for - decrease button
in this case, I use input type range that display a slider :
<input type="range" id="myInputRange" value="15" min="0" max="50" step="1" onchange="document.getElementById('output').textContent=value" ><span id="output">15</span>
(instead of input type number that is not supported by IE)
This seems pretty simple.
(function() {
var count = 0;
var minusButton = document.getElementById("moins");
var plusButton = document.getElementById("plus");
var countBox = document.getElementById("count");
minusButton.onclick = function(e) {
countBox.value = --count;
};
plusButton.onclick = function(e) {
countBox.value = ++count;
};
})();
