in my ember app I'm looking for a way to reference an element in <label for> that works within an {{#each}}-Block. Example:
{{#each}
...
{{view "radio-button" name="options" selectionBinding="options" value="1"}}
<label for="???">Option 1</label>
{{view "radio-button" name="options" selectionBinding="options" value="2"}}
<label for="???">Option 2</label>
...
{{/each}}
Searching the net I found several solutions, but none works within {{#each}}. What is the recommended way to do this?
Thanks in advance.

You can solve this by giving each radio-button a viewName.
{{view "radio-button" name="options" selectionBinding="options" value="1" viewName="option1"}}
<label {{bind-attr for="view.option1.elementId"}}>Option 1</label>
See http://emberjs.jsbin.com/xokurixucapi/1/edit for an example.
Just saw that you actually want it to work in a loop. You can try to bind the viewName to the loop index, did you have a look at this?

I have a form and I want to set default value in the field below but it's not working.
<span>ID User:</span>
<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />
</div>
<div>
<span class="name-in">ID Room:</span>
<input type="text" th:value="${id}" th:field="*{room}" th:errorclass="field-error" />
</div>
I read some topic about this problem and I try to change as given below
th:attr="value = ${session.name}"
But It's still not working. Field ID User is empty. I don't know how to solve this problem.
Although your question contain less information, but i think you want to put default value for all field. If you like to do so change
`<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />`
to
<input type="text" name="userid" value="as your wish" th:errorclass="field-error" />
Instead of changing the html, you should instead set the value of *{userid} in your controller. That way you can keep your html the same:
// Controller
modelObject.setUserId(session.name);
// HTML
<input type="text" th:field="*{userid}" th:errorclass="field-error" />
In HTML we do have option to make a radio button checked by default. Same shown with HTML code snippet below.
<form>
<input type="radio" name="gender" value="male" checked> Male<br>
<input type="radio" name="gender" value="female"> Female<br>
</form>
Do we have similar option available in visual force page as well? If yes how we can achieve it?
Does it require to write a JavaScript code or can achieve through controller?
Please suggest, if solution in code provided will be highly appreciated.
I have find the solution and same providing below.
Visualforce page:
<apex: page controller="SampleCustomController">
<apex:selectRadio value="{!defaultCheck}">
<apex:selectOptions value="Male" name="Male"/>
<apex:selectOptions value="Female" name="Female"/>
</apex:selectRadio>
</apex:page>
Apex controller class:
public class SampleCustomController{
public String defaultCheck{get;set;}
SampleCustomController(){
if(defaultCheck==NULL)
{ defaultCheck='Male';}
}
}
I have a list of similar looking DIVs without any Div ID, except one has a check box checked and others doesn't. What i need is to find the value from a child tag only if a radio button is selected.
Below is a simpler version of my code.
<div class = "XYZ">
<input type="radio" checked>
<input type="hidden" value="This is a great thing 1">
</div>
<div class = "XYZ">
<input type="radio">
<input type="hidden" value="This is a great thing 2">
</div>
Result needed is
This is a great thing 1
Unfortunately the source code cannot be changed.
Your xpath should look for a div that contains the checked input and to get the value for the one that has value attribute.
First selector returns the input, the second returns the value.
//div[.//input[#checked]]/input[#value]
//div[.//input[#checked]]/input/#value
As an alternative you can use the following sibling:
//input[#checked]/following-sibling::input
If you want to also use the class of the parent div:
//div[#class='XYZ']/input[#checked]/following-sibling::input
I'm currently trying to add validation to an angular 2 form, but for some reason I can't get my submit button to disable when the required fields are not filled in.
Here is the code of my form template:
<h1 md-dialog-title>{{title}}</h1>
<form #formCtrl="ngForm">
<md-dialog-content>
<md-input-container>
<input #name md-input placeholder="Name" value="" name="name" focused required>
</md-input-container>
<br />
<md-select #inputtype placeholder="Input type" name="inputtype">
<md-option *ngFor="let inputtype of inputtypes" [value]="inputtype.id">
{{inputtype.name}}
</md-option>
</md-select>
</md-dialog-content>
<md-dialog-actions>
<button type="submit" md-raised-button color="primary" [disabled]="!formCtrl.form.valid">Create</button>
</md-dialog-actions>
</form>
According to several examples, this should work, however the button is never disabled. I've also tried "!formCtrl.valid", also to no avail.
I've tried using non-material design input fields thinking maybe that would be the issue, but it still won't work.
I then tried copy/pasting the following simple example into my application, and even that won't work at all:
http://blog.angular-university.io/introduction-to-angular-2-forms-template-driven-vs-model-driven/
Any ideas as to what might prevent it from working correctly?
Assuming you are using a newer release than Angular 2 final:
You need to add ngModel, which binds the form value based on the name attribute’s value. In your case one is name="inputtype" the other is name="name". So you need to add ngModel to bind the values, and your form should work as you wish! :)
So the following should work (removed a bit of noise from code):
<form #formCtrl="ngForm" (ngSubmit)="save(formCtrl.value)"> //whatever your submit method is
<md-dialog-content>
<md-input-container>
<input md-input name="name" required ngModel>
</md-input-container>
<md-select name="inputtype" required ngModel>
<md-option *ngFor="let inputtype of inputtypes" [value]="inputtype.id">
{{inputtype.name}}
</md-option>
</md-select>
</md-dialog-content>
<md-dialog-actions>
<button type="submit" md-raised-button color="primary" [disabled]="!formCtrl.form.valid">Create</button>
</md-dialog-actions>
</form>
Don't remember when this was introduced, this should be found somewhere in the changelogs which can be useful to have a look at once in a while, since Angular is constantly tweaking things almost in every release. So following that will keep you updated with changes and syntax :)
I need some help with the following issue. I am pretty new to JavaScript so this one is pretty tough for me. Any help would be greatly appreciated!
We have a form for registration that is already in use and I need to make some amends to it to enhance its usability. The form itself already contains several validation scripts and I need to add in a new one - an error message to appear next to the mobile field. I am unable to amend the form HTML itself so I have to do everything by javascript – I need to bind the new function to the submit button so that it fires AFTER all the other validations (field highlight, pop ups), but before the page turns over.
Here is the form (I have just left in the feild i need to amend) :
<form method="post" action="#" id="register_form" class="validate">
<input type="hidden" name="page" value="" />
<input type="hidden" name="unregistered" value="false" />
<fieldset>
<legend>I am a new online customer</legend>
<div class="element">
<label for="mobile_number">Mobile:**</label>
<input name="mobileNumber" type="text" id="mobile_number" title="Please enter at least one number" class="text validate {validate:{minLength:10, eitherOr:'#telephone_number', messages:{minLength:'Please enter a valid phone number (at least #NUM digits long)', eitherOr:'Please enter either your Telephone or Mobile number'}}}" />
</div>
<div class="element continue_shopping_cont submit">
<button type="submit" class="submit button small_button"><span>Register</span></button>
</div>
<input type="hidden" name="secure_from" value="" />
</fieldset>
</form>
Could someone help show me how i am supposed to do this and how is best to target this field?
