Is there way that i could identify where a radio option value gets changed, either thru watch expression on firebug or inspect element ?
i am remote debugging a website and there are 4 radion buttons in the website. We set the CHECKED property for my 4th option as true, it gets checked. But after a sometime(1 sec) my first option gets selected automatically. There are too many javascript code involved and i am not sure where to check.
So is there any way i can do a debug-BREAK when a watch expression fires or any other way to debug this?
You can do this using jquery:
$('input[type=radio][name="inputName"]').on('change',function(){
//#myForm is the id of the form that the radio box in
alert($('input[name="inputName"]:checked', '#myForm').val());
});
This will alert the new value of the radio box when changed JsFiddle

I tried to bind checked attribute value on ion-checbox but the behavior is a bit late.
On my ts file I have an array variable user_id and on my checkbox list i put an action to fill this array depend on which checkbox is checked, and then verify to make the value of checked attribute:
<ion-checkbox [checked]="user_id.includes(user.id) ? true : false" (click)="AddUser(user)"><ion-checkbox>
the user_idis filled and the value of checked change but the checkbox seem not checked, and when i tried to recheck the checkbox, the value change to false but the checkbox seem checked.
I've put some functionality to make condition (example variable type)if the value is true so the checkboxlist is not shown, and with that functionality, when the value of type switch from false to true, the checkbox work well but the behavior is bit late at the moment when the checbox is checked for the first time
TL;DR
click event is working properly with my checkbox and retrieving data is not consistent
Please refer to Ionic documentation on ion-checkbox
using the (click) to capture the action on a checkbox is wrong.
I suggest you use (ionChange) event to trigger your addUser() function.
With [(checked)] binding, it will create an automatic sync between your actions and the values you save.
I have a Tab option like the following image. Total view will share fixed value for both filed of first tab view.
But when I will take value from datepicker or writing manually in input text field, It will not take the fixed value of Total view.
When You clicked on button just make the radio type 'false' . So when you return back radio option will be always unchecked either you click it again.
Just add following jQuery code at the end of your function.
$('input[type="radio"]').each(function () {
$(this).attr('checked', false);
});
I have a form with a radio button asking a question with a Yes/No response. If the user selects Yes, then a drop down appears which is a required field. If the user selects No, then this drop down does not appear.
In the case that the user answers Yes and then chooses a value from the drop-down, then goes back later and changes the answer to No, I want the selected value in the drop-down to be removed (set to '' for example).
How do I do this in AngularJS?
At the moment, what is happening is that the radio box value is set to No, but I am still retaining the value originally selected in the drop down.
I can think of 2 ways:
Watch for the radio button value and set the drop down value to '' when the radio button value is 'No'.
On ng-click of 'No' radio button set the drop down value to ''.
If I am doing it I will choose No. 2 to reduce the watch because watch is a heavy hammer approach.
Summary of problem statement: Radio button html on the browser does not display the checked attribute, but Firebug indicates that the radio's checked attribute is set as checked.
Tested on
Broswer: FF 3.6.18 and IE8
jQuery: 1.5
MVC3 (Razor)
Details
Using MVC3 (with Razor) I'm rendering the following radio buttons from the server. The desired functionality is that on checking one radio, the other should be unchecked and vice-versa. In other words, the user is allowed to only select one option - say val1 or val2.
<div id="myRadioList">
<div>
<input type="radio" value="val1" onclick="updateFunctionCalledHere(this)" name="myRadioName" id="myRadioName_val1" checked="checked">
</div>
<div>
<input type="radio" value="val2" onclick="updateFunctionCalledHere(this)" name="myRadioName" id="myRadioName_val2">
</div>
</div>
What I'm observing is that if the user toggles the radio selected, the newly selected radio (let's say myRadioName_val2) is shown to be checked using firebug but the html still reflects the other radio button as checked. Because of this, some other validations are failing.
I've tried literally removing all checked attributes of both the radio buttons and then just check the one that's clicked.
This is what I'm doing to set the currently clicked radio, that is not working:
$("#myRadioList > div > input[value='myRadioName_val2]').attr('checked', 'checked');
I'm simplifying my code to avoid posting unnecessary details.
The checked attribute in HTML is the default value.
The checked property in JavaScript refers to the current state of the radio button.
Generally, it's best to let the browser handle the checked state of radio buttons and checkboxes rather than setting it yourself, otherwise you run into these kinds of problems. It's safe to get the current state via prop("checked") as already suggested, or through .is(":checked").
You may also want to consider using syntax like $('#myRadioList').find('input[value="myRadioName_val2"]') or better yet, $('#myRadioName_val2'), as child selectors in jQuery can be rather slow, since they are read right to left.
You should use
$("#myRadioList > div > input[value=myRadioName_val2]").prop('checked', true);
Well, you do have a syntax error withing the jQuery selector. It should be:
$('#myRadioList > div > input[value="myRadioName_val2"]')
I'm currently working on a Lotus Notes solution. We're just using Web forms so client side operations are done via Javascript.
What I want to accomplish is to reset a Group of Radio Buttons. There are 3 possibilities and I want to choose none. (A 'none of them' possibility would be preferable, I know but we are required to reset them)
I currently use:
//Unchecks a single group of Radio Buttons
//groupname - the name attribute of the group which selection needs to be unchecked
function clearRadioButtonGroup(groupName) {
for(i=0;i<document.forms[0].elements[groupName].length;i++) {
document.forms[0].elements[groupName][i].checked = false;
}
}
The problem with this routine is, the Radiogroup gets reset, but on a form submit the old value gets submitted. Any suggestions?
What version of Domino are you using? Since 7.x (I think) a %%Surrogate field gets generated as a hidden field in your HTML that you'll be able to reset, so after deselecting all of the radio button options, you can then clear out the %%Surrogate field and you should then avoid having to select a "None of the above" option.
Matt
The problem is that clearing the radio buttons make no information about them appear in the submitted form data, and Domino seems to interpret that as no change to the field rather than clear the field.
I haven't found any solution to this I really like, but I can think of two options:
Change the radio buttons to include a no choice option.
The alternative is a bit clumpsy:
Add an editable field to the form to use as a flag, hide it from the web browser with css.
Have clearRadioButtonGroup also set the flag field to something.
Have the onChange event of the radio buttons clear the flag field.
In a WebQueryOpen agent, set the radio buttons field to empty if the flag field is non-empty.
Another alternative could be to uses some clever javascript/css trick to hide the no choice option and have clearRadioButtonGroup simply set that choice.
Are you certain that the old value is actually being submitted? Perhaps it just isn't being updated (erased) in the NotesDocument you're editing? Just a hunch...
BTW, you can download a program called Fiddler that will let you inspect the HTTP POSTs, and you can confirm that the POST data doesn't contain any values for that radio button group. That might help narrow down the problem.
Put the following pass thru HTML code on your form:
<input type="hidden" name="FieldName" id="FieldID" value="">
(FieldName and FieldID are the name and id of your radio field on the form)
When you reset your radio through Javascript and submit your document, the field will be reset to blank.
