Using can 2.2 : I'm having trouble getting a radio input field to be checked by default when also using the can-value attribute.
The relevant part of the stache template looks like this:
<input type="radio" name="visibility" value="corporate" can-value="reportData.visibility" checked="checked"/>
The relevant part of my viewModel looks like this:
can.Map.extend({
reportData = {
visibility: 'corporate',
}
});
I want the input value to be live-bound to my view model. According to the can 2.2 docs, I can use the can-value attribute on an input to reference a property on my view model and keep it in sync with the value of the input's value. My problem is the checked="checked" doesn't result in the input being checked by default, though the value on the input item (corporate) is being correctly live-bound. If I remove the can-value attribute, the check appears by default. How can I get both live-binding and a checked input by default with the help of can-value?

I want to dynamically set the input datetime step granularity using aurelia binding.
In my time.js:
timeStep = "1";
In my time.html:
The following works correctly:
<input type=datetime-local value="2017-01-01T00:00:00" step="1" value.bind="formParameters.timeFrom" >
${timeStep}
However when I try to set the step using my variable - it doesn't seem to work:
<input type=datetime-local value="2017-01-01T00:00:00" step="timeStep" value.bind="formParameters.timeFrom" >
${timeStep}
You can see I have lost the seconds granularity. When I inspect the element, it comes out as:
<input type="datetime-local" value="2017-01-01T00:00:00" step="timeStep" value.bind="formParameters.timeFrom" class="au-target" au-target-id="37">
Where timeStep should be "1".
To bind any HTML attribute to a property in your viewModel - you need to use .bind.
<input type=datetime-local value="2017-01-01T00:00:00" step.bind="timeStep" value.bind="formParameters.timeFrom">
Aurelia will assume anything in a .bind attribute is a property of your viewModel class and bind them accordingly. You can use .bind on any (as far as I know) HTML attribute.
I have 2 forms that I am testing using TestStack.Seleno. Both forms have a checkbox that is mandatory. The first form has (including the checkbox) 5 fields. I can use TestStack.Seleno to create a passing test with valid data. I set the checkbox like this:
Input.TickCheckbox(f=>f.Accept,form.Accept);
On my other form which has 10 or so fields, when I try to set the checkbox to be ticked (using the same code) nothing happens. However when I try
var acceptCheckBox = Find.Element(By.Name("Accept"),new TimeSpan(0,0,0,50));
if (form.Accept)
{
acceptCheckBox.Click();
}
I get error "Element is not currently visible and so may not be interacted with"
Element is clearly visible and is not injected in using javascript.
I am using latest version of TestStack.Seleno from github.
Any ideas?
So I have managed to figure out what the issue is and have a work around, however I cannot explain why it works on the other form. The mandatory Accept field has html generated by mvc that looks like
<div>
<input class="check-box" data-val="true" data-val-mustbetrue="The Accept our field is required" data-val-required="The Accept our field is required." id="Accept" name="Accept" type="checkbox" value="true"><input name="Accept" type="hidden" value="false">
<label for="Accept">
Accept our Please accept our Terms and Conditions
</label>
<span class="field-validation-valid" data-valmsg-for="Accept" data-valmsg-replace="true"></span>
</div>
So you have the checkbox and hidden field both with id Accept, I suspect in code seleno is picking up the hidden field and setting value, so I updated my code todo
var acceptCheckBox = Find.Element(By.CssSelector("#Accept.check-box"));
acceptCheckBox.Click();
Now everything works.

Sorry but I am new to C# and ASP.NET and I saw alot of posts about this problem but I quite didn't get it. I am trying to understand how to pass a GET parameter to an action thru HTML.ActionLink:
here is the the URL:
http://localhost:36896/Movies/SearchIndex?searchString=the
and my CSHTML page should look like this:
<input type="Text" id="searchString" name="searchString" />
#Html.ActionLink("Search Existing", "SearchIndex", new { searchString = "the"})
this hard coded parameter "the" is actually working, but how can I select the input element with id=searchString, with something like document.getElementById("searchString").value
Thanks,
If the value you want to send as GET parameter is not known on the server you cannot use the Html.ActionLink helper to add it. You need to use javascript to manipulate the existing link and append the parameter.
It looks like you have an input field that contains a search string and you want to send the value entered in this field to the server. A better way to handle this scenario is to use an HTML form with method="GET" instead of an ActionLink. This way you don't need to use any javascript - it's part of the HTML specification:
#using (Html.BeginForm("SearchIndex", "Movies", FormMethod.Get))
{
#Html.EditorFor(x => x.SearchString)
<button type="submit">Search</button>
}
Now when you click on the Search button the value entered in the SearchString field will automatically be sent to the SearchIndex action:
http://localhost:36896/Movies/SearchIndex?searchString=the
But if you absolutely insist on using an ActionLink you will have to write javascript to manipulate the href of the existing link when this link is clicked in order to append the value to the url. It's an approach I wouldn't recommend though because the HTML specification already provides you this functionality throughout HTML forms.
This makes the #Html.EditorFor refer to the Title field of the object, kinda in a random way but it works!
#using (Html.BeginForm ("SearchIndex", "Movies", FormMethod.Get))
{
#Html.EditorFor( x => x.ElementAt(0).Title)
<button type="submit">Search</button>
}
Still couldn't pass input parameter to the URL in the GET.
EDIT:
FINAL SOLUTION:
#Html.TextBox("SearchString")
<button type="submit">Filter</button>
and on the controller side, switch the input parameter. Basically it will automatically recognize the passed parameter.
public ActionResult SearchIndex(string searchString)
{
...
}
I want to be able to reset all text fields to their default values when a button is clicked.
What I've done so far is query for all text fields and bind a function I wrote called 'textChanged' to the change event as follows:
require(["dojo/on","dojo/query"], function(on,query){
query(".Text").on("change",textChanged);
});
The function is defined as follows:
function textChanged(newVal)
{
...
}
I found I can reset the value in the body of the function by doing the assignment:
newVal.target.value = newVal.target.defaultValue;
If this function is triggered by a change event.
What I want to do is if a button is clicked, then I want to execute the newVal.target.value = newVal.target.defaultValue and am having trouble getting the context correct.
I've tried preserving the 'this' variable when it is called as well as preserving the 'newVal' parameter. If I try setting the value outside of the the context, then the update doesn't preserve. I've tried setting the 'this' value to some other value (nt = this) and the newValue to another variable (nv = newValue) and then I want to execute:
nv.target.value = nv.target.defaultValue;
and although it clears the field on the form, when the form is submitted, its actual value is still the manually modified value. I noticed that the 'this' is different from when I textChanged is called from the change event verses when I call it directly in my button clicked context.
I tried calling it using 'hitch' to set the context of this to its value that it had from the change event, but that doesn't seem to set the correct context:
require(["dojo/on", "dojo/_base/lang"], function(on, lang) {
lang.hitch(nt, textChanged(nv));
});
To be precise - inside textChanged I display the value of 'this' using console.log(this);
When textChanged is invoked when the text changes from the UI, 'this' is:
Yet when it is invoked from clicking my button that calls it via the
lang.hitch(nt, textChanged(nv));
'this' is:
Window fauxRedirect.lsw?applicationInstanceId=guid%3A1eae6af09bf6f543%3A-6644aeb4%3A13a8a4c429e%3A-7ffe&zWorkflowState=2&zTaskId=p1&applicationId=2&zComponentName=CoachNG&zComponentId=3028.b1094dc3-da2b-461a-8d56-f6444891c174&zDbg=2#%20%20
I've confirmed that 'nt' is indeed the same '
So, I'm trying to execute the textChanged function such that 'this' is set to that value.
Or, if there is a better way to reset a field to its default from another control - that would work as well.
Thanks in advance.
I'm not sure of the full context of what you are trying to do, so don't know if this answers your question?
You can reset all of the widgets within a form to their default value as long as they are wrapped in a dijit/form/Form widget. If all the widgets are wrapped correctly it should be a simple matter of calling reset() on the form.
NB: This will not work for native elements (ie. standard <input> or <textarea> fields, they must be dijit/form/TextBox ...etc).
eg:
<form data-dojo-type="dijit/form/Form" data-dojo-id="theForm">
<label for="field1">Field 1:</label>
<input
type="text" id="field1" name="field1"
data-dojo-type="dijit/form/TextBox" value="default1"
/><br />
<label for="field2">Field 1:</label>
<input
type="text" id="field2" name="field2"
data-dojo-type="dijit/form/TextBox" value="default2"
/>
<br /><br />
<button
type="button"
data-dojo-type="dijit/form/Button"
onclick="theForm.reset();"
>Reset</button>
</form>
Clicking the reset button here should reset the fields to: field1="default1" and feield2="default2".
The form is calling each widget's reset() method. If you create your own widgets you need to ensure that their reset() method works correctly (as well as the _getValueAttr() method for setting their value).
I have a Windows 8 app with a template that contains a div I want to show or hide based on the value of a property inside a data-win-control="WinJS.Binding.Template". I have tried the following without luck:
<div data-win-bind="visible: isMore"> ..content... </div>
where isMore is a boolean property of the databound item.
How can I do that? I guess the visible property does not exist?
You are right - the visible property doesn't exist, but you can control the appearance using CSS and a binding converter.
First, use WinJS.Binding.converter to create a converter function that translates a boolean to a value value for the CSS display property, like this:
var myConverter = WinJS.Binding.converter(function (val) {
return val ? "block" : "none";
});
Make sure that the function is globally available - I use WinJS.Namespace.define to create collections of these converters that I can get to globally.
Now you can use the converter in your data binding to control the CSS display property, like this:
<div data-win-bind="style.display: isMore myConverter"> ..content... </div>
