i have a template as below
<script id="ActionTemplate" type="text/x-jquery-tmpl">
<tr>
<td> <a href="#" OnClick="setActionId(${action_id}, ${project_id}, ${merchant_id}, ${channel_id}, ${customer_id})" >${action_id}</a></td>
<td>${priority} </td>
<td>${date_to_display} </td>
<td> ${date_from}</td>
<td>${action_title} </td>
<td> ${status()} (${percentage_completed}%)</td>
<td> ${hours}</td>
<td>${contactFrom} </td>
<td>${contactTo} </td>
</tr>
</script>
in above ${status()} calls the function status which returns a string like this
<script type="language/javascript">
function status(){
return "some_string";
}
</script>
my problem is i hav to send a value from template where the status function is called..value like ${action_status}...
all the values that are in the template like ${priority},${hours},etc are binded to template in a pagemethod...
need a solution
You can pass values from your data to function using the $data keyword. Change the following line in your template like this :
<td> ${status($data.action_status)} (${percentage_completed}%)</td>
assuming 'action_status' is the correct property name from your data...

I have used below code but it is not working as i am new i need your guidence
#76484 i have used this ``` {{#if userData.length != 0 }}
{{var i =1;}}
{{userData.forEach(function(data))}}
<tr>
<td>{{=i;}}</td>
<td>{{= data.fullName}}</td>
<td>{{= data.emailAddress}}</td>
<td>{{= data.city}}</td>
<td>{{= data.country}}</td>
<td>{{= data.Dimension_4_Score}}</td>
<td>{{= data.Total_Score_Persentage}}</td>
</tr>
{{i++; })}}
{{else{} }
<tr>
<td colspan="7">No Data Found</td>
</tr>
{{}}}
</table>
</div>
</body> ``` but it is not working
The primary difference between your embedded JS example and Handlebars is that Handlebars does not execute arbitrary JavaScript, like your .forEach loop. Instead, Handlebars provides helpers to allow you to do things like conditionals and iteration.
First, we will tackle your condition, if (userData.length != 0). Handlebars has a #if helper which we could use to check if userData has a truth (greater than 0) length. The result would be:
{{#if userData.length}}
{{! TODO: output each user data}}
{{else}}
<tr>
<td colspan="7">No Data Found</td>
</tr>
{{/if}}
Secondly, Handlebars has an #each helper which is used for looping over collections as you are doing with your userData.forEach(function(data) { /*...*/ } code. For your purposes, the syntax would be:
{{#each userData}}
<tr>
<td>{{ #index }}</td>
<td>{{ fullName }}</td>
<td>{{ emailAddress }}</td>
<td>{{ city }}</td>
<td>{{ country }}</td>
<td>Edit</td>
<td>Delete</td>
</tr>
{{/each}}
Notice how we are evaluating the properties of each object in our userData array. There is no =. We just wrap the property name in double-handlebars, like {{ fullName }}. Handlebars handles the execution context within the #each so that we are always referring to the current iteration of our array.
Also notice the {{ #index }}. This is a special variable provided by Handlebars to give us the current iteration index within our #each loop. It is zero-index, so our output will be slightly different from your ejs example because you initialized your counter at 1.
Unfortunately, if we want our indexes to be one-based, we will have to write a custom helper to this. Our helper would just need to take a number, #index, and increment it by 1. It would look like:
Handlebars.registerHelper('increment', function (num) {
return num + 1;
});
And we would update our template to make use of it:
{{increment #index }}
I have created a fiddle with the final example for your reference.
Hi I have problem with my MVC application.
I would like click on ActionLink > load data from server > and insert data to div in same page.
But my code still loads content on new page and I don`t have idea why. Anybody to help me ?
This is my Index.cshtml in HomeController,
#model IEnumerable<Kango_kmen.KangoKmenWS.WSEntityInfo>
#Content.Script("jquery-1.9.1.min.js", Url)
#Content.Script("jquery.unobtrusive-ajax.min.js",Url)
#Content.Script("jquery.unobtrusive-ajax.js",Url)
#Content.Script("myScript.js",Url)
#section Entities{
<table>
<tr>
<th>
<input type="submit" value="zobrazit" />
</th>
<th>
iD
</th>
<th>
name
</th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Ajax.ActionLink("..", "CheckEntity", new { id = item.iD },
new AjaxOptions{ UpdateTargetId="properties",
HttpMethod="GET",
InsertionMode=InsertionMode.InsertAfter,
})
</td>
<td>
#Html.DisplayFor(modelItem => item.iD)
</td>
<td>
#Html.DisplayFor(modelItem => item.name)
</td>
</tr>
<tr>
<td>
<div id="properties">
</div>
</td>
</tr>
}
</table>
}
#section PropertyInfo{
<p>Property info</p>
}
#section Properties{
<p>properties</p>
}
And here is my Controller in HomeController
public PartialViewResult CheckEntity(int id)
{
var model = WSConnect.getEntityInfo(id);
if(model !=null){
return PartialView("CheckEntity", model.property);
}
var modell = new WSEntityInfo[0];
return PartialView("CheckEntity", modell);
}
and ChecktEntity is the Partial view but everytime I click on ActionLink controller load url: /Home/ChceckEntity/1000 for exmaple on view data on this new page "(
There are 2 things wrong with your code:
You have included the jquery.unobtrusive-ajax.js script twice, once the minified version and once the standard version. You should include it only once
The jquery.unobtrusive-ajax.js is not compatible with jquery 1.9.1 because one of the breaking changes in jQuery 1.9 is that the .live() method was removed and the jquery.unobtrusive-ajax.js script relies on it. If you look at your javascript console you would see the following error: The .live method is undefined.. So if you want to use the unobtrusive AJAX functionality in ASP.NET MVC you will have to downgrade the version of jQuery. For example the 1.8.3 version should be fine.
So:
#model IEnumerable<Kango_kmen.KangoKmenWS.WSEntityInfo>
#Content.Script("jquery-1.8.3.min.js", Url)
#Content.Script("jquery.unobtrusive-ajax.min.js", Url)
#Content.Script("myScript.js", Url)
Also please learn how to debug your javascript code. Use a tool such as FireBug or Chrome developer toolbar where all those errors will be shown.
I am a beginner in ASP.Net MVC 3
I will make a dynamic array initially must show me the first ten elements, and when I click view more displays all array elements
here's what I did:
<table>
#foreach (var tweet in Model)
{
<tr>
<td>
<img alt="" src="#tweet.ProfileImageUrl" />
<br />
<input id="rowIDs" type="checkbox" />
</td>
<td>
<strong>#tweet.Name</strong>
<br />
Friends: <strong>#tweet.FriendsCount</strong>
</td>
</tr>
}
</table>
thank you in advance
You have to put 10 items in the controller,
return View(array.Take(10).Skip(page));
Do not use the button anymore. Use the pager.
You need to peredovat variable Pag.
The easiest way(on my opinion) is to create a anchor to the page, itself, with a query string.
Your View must have an anchor like this:
All Comments
And relative controller(HttpGet, not HttpPost(if it has any)) must be something like this:
public ViewResult List(bool fullComment=false)
{
if (fullComment)
return View(dbContext.EntityList.ToList());
else
return View(dbContext.EntityList.Take(5).ToList());
}
Note: if the page has querystring already, in creating anchor link, in view, you must pay attention to this.
Here is the code of my knockout template:
<script type="text/html" id="row-extension-template">
{{each items}}
<tr class="tr_element">
<td><span>${name}</span></td>
</tr>
{{/each}}
</script>
This piece of code is embedded in my jsp file.
When I see the html source-code generated by the server is look like this:
<tr class="tr_element">
<td><span></span></td>
</tr>
But I want this:
<tr class="tr_element">
<td><span>${name}</span></td>
</tr>
I want the text ${name} to be written in the html generated. How can I do that with Spring-mvc?
I have solved with this:
<script type="text/html" id="row-extension-template">
{{each items}}
<tr class="tr_element">
<td><span><%="${name}"%></span></td>
</tr>
{{/each}}
</script>
That way when I see the html source code I get:
<tr class="tr_element">
<td><span>${name}</span></td>
</tr>
Your page is loaded by using a Controller and RequestMapping in Spring. Find the method annotated with #RequestMapping that corresponds with your page. You then need to add the name to the model within that method.
model.addAttribute("name", "Some Name Value");
http://static.springsource.org/spring/docs/2.5.x/reference/mvc.html
Write an object to the Model with key name, as in:
#RequestMapping("foo.do")
public String myHandler(Model model) {
String name = "something";
model.addAttribute("name", name);
return "foo";
}
I am trying to render a table, using EditorFor, and a partialview, I think.
I have a model with a List<> property defined like this:
public List<TransactionSplitLine> TransactionSplitLines { get; set; }
The idea is that a user selects a few drop downs and enters a value into an edit box, and clicks a button. The model goes back to the controller, and the controller adds the entered values to the List<>
[HttpPost]
public ActionResult AccountTransaction(AccountTransactionView model)
{
var reply = CreateModel(model);
if (model.CategoryIds != null)
{
foreach (var c in model.CategoryIds)
{
reply.TransactionSplitLines.Add(new TransactionSplitLine { Amount = "100", Category = "Test Category", SubCategory = "Test More", CategoryId = int.Parse(c) });
}
}
reply.TransactionSplitLines.Add(new TransactionSplitLine { Amount = "100", Category = "Test Category", SubCategory = "Test More", CategoryId = 1 });
return View("AccountTransaction", reply);
}
Ignore the CreateModel. It simply sets up some data. Also, I am hardcoding data. This will eventually come from some form values.
The model is then returned to the same screen, allowing the user to ender more data. Any items in the List<> are read and a Table is rendered. I also have to store the current listen item values in hidden fields, so that they can be submitted back, along with the new data entered, so that the list can grow each time the user adds data.
The view is defined like this:
<table width="600">
<thead>
<tr class="headerRow">
<td>
Category
</td>
<td>
Sub Category
</td>
<td>
Amount
</td>
</tr>
</thead>
<tbody>
<%=Html.EditorFor(m=>m.TransactionSplitLines) %>
</tbody>
</table>
This is my first attempt with EditorFor...
My View is in a folder 'Views/BankAccount/AccountTransaction.aspx
I have created a ascx in Views/Shared/TransactionSplitLines.ascx
The code for the ascx is like this:
<%# Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<BudgieMoneySite.Models.TransactionSplitLine>" %>
<tr>
<td>
<%=Model.Category %>
<%=Html.HiddenFor(x => x.CategoryId)%>
</td>
<td>
<%=Model.SubCategory %>
<%=Html.HiddenFor(x => x.SubCategoryId)%>
</td>
<td>
<%=Model.Amount %>
<%=Html.HiddenFor(x => x.AmountValue)%>
</td>
</tr>
This is data
The 'This is data' is just test stuff, which is never rendered.
When I run this, all that happens is that my output is rendered as:
<table width="600">
<thead>
<tr class="headerRow">
<td>
Category
</td>
<td>
Sub Category
</td>
<td>
Amount
</td>
</tr>
</thead>
<tbody>
Test Category
</tbody>
</table>
It seems like the ascx isn't being used? I'd expect to see the 'This is data' text. But, nothing. Hopefully you can see an obvious fault?
Your editor template should be either:
~/Views/Shared/EditorTemplates/TransactionSplitLine.ascx
or:
~/Views/BankAccount/EditorTemplates/TransactionSplitLine.ascx
The name of the ascx is always the type name of the collection item (TransactionSplitLine and not TransactionSplitLines) and it should be situated at ~/Views/Shared/EditorTemplates or ~Views/ControllerName/EditorTemplates.
Or if you want to use a custom editor template name:
<%= Html.EditorFor(m=>m.TransactionSplitLines, "~/Views/foo.ascx") %>
Or use UIHintAttribute on your model.
