I have a modal dialog (Bootstrap) that has a list-group with custom list-group-items inside of it (populated by loop using append after adding data from my server).
Inside each list-group-item, I have a Checkbox that will be used to "select" the result. As I populate the items, I hook up the JQuery click event to the respective Checkbox:
// Add to search results
$('#search-results').append(
'<a id="centroid-list-item-' + featureAttrs['ObjectID'] + '" href="\\#"' + 'class="list-group-item" style="outline: 0">' +
'<table style="background: transparent">' +
'<tr>' +
'<td>' +
'<input id="centroid-checkbox-' + featureAttrs['ObjectID'] + '" type="checkbox" value=""> ' +
'</td>' +
'<td>' +
'<h4 class="list-group-item-heading">' +
featureAttrs['UNIQUEID'] +
'</h4>' +
'<p id="centroid-item-text-' + featureAttrs['ObjectID'] + '"' + 'class="list-group-item-text">' +
featureAttrs['NAME'] +
'</p>' +
'</td>' +
'</tr>' +
'</table>' +
'</a>'
);
// When the DOM is ready, add event
$(document).ready(function () {
$('#centroid-checkbox-' + featureAttrs['ObjectID']).click(function (event) {
var objectId = $(this).attr('id').replace(/^\D+/g, '');
console.log(objectId + " was clicked");
if ($(this).is(':checked')) {
// Enable the 'Set Target' button
$('#btn-set-target').removeAttr('disabled');
// Disable all other choices
$('[id^="centroid-checkbox-"]').each(function (event) {
console.log("Picked up values for checkboxes");
if ($(this).attr('id') != ('centroid-checkbox-' + objectId)) {
$(this).attr('disabled', true);
}
});
}
else {
$('#btn-set-target').attr('disabled', 'disabled');
// Enable all text boxes
$('[id^="centroid-checkbox-"]').each(function () {
if (this.attr('id') !== ('centroid-checkbox-' + objectId)) {
this.removeAttr('disabled');
}
});
}
});
});
The problem I am having is that when I call $('[id^="centroid-checkbox-"]')
it is returning undefined. However, at the time is gets called, there are about 30 "centroid-checkbox-XXXXX" checkboxes. What am I doing wrong here?
The $
function never returns undefined
.
But this
in the callback you pass to each
is an element, not a jQuery object.
Which means you must use this.id
instead of this.attr('id')
and $(this).removeAttr('disabled')
instead of this.removeAttr('disabled')
(and you probably want this.disabled=false
or $(this).prop('disabled', false)
).
objectId never gets defined because you need to quote enclose the regular expression you're using for replace():
var objectId = $(this).attr('id').replace(/^\D+/g, '');
should be:
var objectId = $(this).attr('id').replace('/^\D+/g', '');
