While building a table, I'm binding onClick handler to td element:
<td data-person-id={person.id} onClick={this.removePerson}>
<button type="button" className="btn btn-default btn-default">
<span className="glyphicon glyphicon-remove" aria-hidden="true">Remove</span>
</button>
</td>
But when an event is handled, it points to button or span elements but not td one so it means I can't just get needed data-person-id attribute. How can I fix it?

Thank you.
<td>
<button
type="button"
className="btn btn-default btn-default"
onClick={this.removePerson.bind(this, person.id)}>
<span className="glyphicon glyphicon-remove" aria-hidden="true">Remove</span>
</button>
</td>
Let your button element handle onClick (otherwise you might have weird behavior like clicking outside of the button but inside of td triggering an event) and bind the id to the context.
Then, later on your removePerson function access id directly:
...
removePerson(id) {
// do stuff
}
...

I have four buttons:
<button id="button-yardSize" class="btn btn-success" value="2"><h1>2</h1></button>
<button id="button-yardSize" class="btn btn-success" value="4"><h1>4</h1></button>
<button id="button-yardSize" class="btn btn-success" value="6"><h1>6</h1></button>
<button id="button-yardSize" class="btn btn-success" value="8"><h1>8</h1></button>
And I want to capture the value of the button clicked so that I may add it later with another button and add them together.
I added this for the JS:
var inputYardSize = $("#button-yardSize").on("click", function(){
$("#button-yardSize").val();
console.log(inputYardSize);
});
I read that I may need to use .attr instead, however not sure how to add a custom attribute to the buttons?
First of all, you should use a class, not an ID. IDs should be unique, and $("#button-yardSize") will only select the first button.
In the event listener you can use this to refer to the button that was clicked.
You need to assign the inputYardSize variable inside the function. .on() just returns the jQuery object you're binding the handler to, not the value from inside the function.
$(".button-yardSize").on("click", function() {
var inputYardSize = $(this).val();
console.log(inputYardSize);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="btn btn-success button-yardSize" value="2"><h1>2</h1></button>
<button class="btn btn-success button-yardSize" value="4"><h1>4</h1></button>
<button class="btn btn-success button-yardSize" value="6"><h1>6</h1></button>
<button class="btn btn-success button-yardSize" value="8"><h1>8</h1></button>
EDIT: You should use ID for unique elements and class for repeating element.
So if you would replace the ID with class on the button, the code should look like this:
Remove the declaration from the beginning and instead use it to store the values inside the click function.
In this way, you will have the value of the clicked button with the specified class.
$('.button-yardSize').on('click', function(){
var inputYardSize = $(this).val();
console.log(inputYardSize);
})
The id of each element has to be unique
<button id="button-yardSize1" class="btn btn-success" value="2"><h1>2</h1></button>
<button id="button-yardSize2" class="btn btn-success" value="4"><h1>4</h1></button>
The JS function is incorrect, you need a click handler which will log the button value
$("#button-yardSize1").on("click", function(){
inputYardSize=$("#button-yardSize1").val();
console.log(inputYardSize);
});
How to disable a button on click and replace that button with another button with different function using AngularJS?
The following is my button,
<button type="submit" class="btn btn-small btn-default"
ng-disabled="isteam==0 || secondEdit" ng-click="editSetting()">
<span class="glyphicon glyphicon-edit"></span> Edit Setting</button>
you can use a state setting, say $scope.showFirstButton=true to control when to show the submit button:
<button ng-show="showFirstButton" type="submit" class="btn btn-small btn-default" ng-disabled="isteam==0 || secondEdit" ng-click="editSetting()">Edit Setting</button>
and another button, showing them alternatively:
<button ng-show="!showFirstButton" type="submit" class="btn btn-small btn-default" ng-click="doSomethingElse()">Seccond Button</button>
In the controller method $scope.editSetting() you change the value of the state: $scope.showFirstButton = !$scope.showFirstButton'.
Edit: if you need to revert the state of the buttons, do the same thing in the second method:
$scope.doSomethingElse = function(){
//some cool things happen here, and:
$scope.showFirstButton = !$scope.showFirstButton
}
and this will get back the first button and hide the second.
i am using bootstrap btngroup to select one value ..how can i display that selected value ?? here is my code.
<div class="input-group">
<div id="radioBtn" class="btn-group">
<a class="btn btn-primary btn-sm active" data-toggle="fun" data- title="Y">YES</a>
<a class="btn btn-primary btn-sm notActive" data-toggle="fun" data-title="X">I don't know</a>
<a class="btn btn-primary btn-sm notActive" data-toggle="fun" data-title="N">NO</a>
</div>
<input type="hidden" name="fun" id="fun">
</div>
and JS
$('#radioBtn a').on('click', function(){
var sel = $(this).data('title');
var tog = $(this).data('toggle');
$('#'+tog).prop('value', sel);
$('a[data-toggle="'+tog+'"]').not('[data- title="'+sel+'"]').removeClass('active').addClass('notActive');
$('a[data-toggle="'+tog+'"][data-title="'+sel+'"]').removeClass('notActive').addClass('active');
})
Tidy your code - remove the spaces in your data- title attribute, in both the HTML and JS, as these are causing it to break.
Add a <div id="display"></div> in your HTML somewhere and style it how you like.
Add this line to your JS click handler: $('#display').html(sel);
Here's a demo.
If you'd prefer the result to be the text of the radio button instead of the value, use $('#display').html($(this).html()); instead in step 3.
Done.
Not sure if this is what you mean, but to get the value (or text) from a clicked button in a button group, I use for example.....
HTML
<div id="aBtnGroup" class="btn-group">
<button type="button" value="L" class="btn btn-default">Left</button>
<button type="button" value="M" class="btn btn-default">Middle</button>
<button type="button" value="R" class="btn btn-default">Right</button>
</div>
<p>
<div>Selected Val: <span id="selectedVal"></span></div>
JS
$(document).ready(function() {
// Get click event, assign button to var, and get values from that var
$('#aBtnGroup button').on('click', function() {
var thisBtn = $(this);
thisBtn.addClass('active').siblings().removeClass('active');
var btnText = thisBtn.text();
var btnValue = thisBtn.val();
console.log(btnText + ' - ' + btnValue);
$('#selectedVal').text(btnValue);
});
// You can use this to set default value upon document load
// It will fire above click event which will do the updates for you
$('#aBtnGroup button[value="M"]').click();
});
CONSOLE OUTPUT
Left - L
Middle - M
Right - R
Hope this helps
Plunker here
my button is defined:
<td>
<button type="button" class="btn btn-danger" id="${machine.uid}">
<spring:message code="vending.generic.delete" />
</button>
</td>
I want to add an event handler to the button.
I tried this:
$(document).on("click",'.btn btn-danger',function(e){
....
}
You can use another dot . without space to target element by multiple classes name:
$(document).on("click",'.btn.btn-danger',function(e){
....
}
Actually .btn btn-danger is an invalid selector, you have to merge by using a dot, so that the meaning becomes "Hey select all elements which contains class btn and class btn-danger"
Try,
$(document).on("click",'.btn.btn-danger',function(e){
....
}
Is that possible when the user add a new row and by clicking on the cancel button(without put any data), the row will be deleted.
Otherwise how can I change the cancel button code, because this one use the default xeditable code of angularJS.(Or maybe how can I call the delete function if the row is empty?)
This is the EXAMPLE.
HTML for the cancel button:
<button type="button" ng-disabled="rowform.$waiting" ng-click="rowform.$cancel()" class="btn btn-default">
cancel
</button>
You may call your own function. To achieve this you should change your html like this:
<button type="button" ng-disabled="rowform.$waiting"
ng-click="cancelAdvice(rowform, $index)"
class="btn btn-default">
cancel
</button>
As you can see there is a new function with the form and the current index as parameter. In your controller you have to define this function:
$scope.cancelAdvice = function(rowform, index){
console.log(rowform, index);
$scope.removeUser(index);
rowform.$cancel();
}
Now you can do your own stuff and call the form $cancel if you are done.
Alternatively if you look at xeditable.js you'll see that $cancel() internally calls $oncancel() which looks for oncancel attribute on the form and calls the function supplied in it. So instead of handling the form in the controller you could have:
<form editable-form name="rowform" onbeforesave="saveRole($data, $index)" oncancel="removeIfNewRow($index)" ng-show="rowform.$visible" class="form-inline" shown="inserted == role">
<button type="submit" ng-disabled="rowform.$waiting" class="btn btn-primary">
save
</button>
<button type="button" ng-disabled="rowform.$waiting" ng-click="rowform.$cancel()" class="btn btn-default">
cancel
</button>
</form>
