Mixing
jQuery for parent select
I'm trying to change the background color of the select box when they click on the select box but can't find what is wrong. I thought it would be something like
$(this.parent).css('background','#fff');
$('select.flag').change(function(){
var callid = $(this).data('callid');
var flag = $(this).val();
$.ajax({
url: "/calls/update/flag",
type: "POST",
data: {flag: flag, callid : callid},
success: function(result) {
$(this.parent).css('background','#fff');
},
error: function() {
alert("Error. Please try again.");
}
});
});
<div class="pure-g">
<div class="pure-u-1-4">
<select data-callid="2" class="flag" style="">
<option value="flag">Flag</option>
</select>
</div>
</div>jquery

The issue is that the value of this changes within the success callback and is no longer the element the event originated from. There are a few ways to fix this.
Set the context
Providing the context option lets you specify to jQuery what the this should be within the callbacks.
$.ajax({
url: "/calls/update/flag",
type: "POST",
data: {
flag: flag,
callid: callid
},
context: this,
success: function(result) {
$(this).parent().css('background', '#fff');
},
error: function() {
alert("Error. Please try again.");
}
});
Use a variable
You could also make your own variable to store it in that does not change.
var that = this;
$.ajax({
url: "/calls/update/flag",
type: "POST",
data: {
flag: flag,
callid: callid
},
success: function(result) {
$(that).parent().css('background', '#fff');
},
error: function() {
alert("Error. Please try again.");
}
});
Use the already existing event
The event already has a reference to the element on it, so you do not have to create your own variable.
$('select.flag').change(function(e){
$.ajax({
url: "/calls/update/flag",
type: "POST",
data: {
flag: flag,
callid: callid
},
success: function(result) {
$(e.target).parent().css('background', '#fff');
},
error: function() {
alert("Error. Please try again.");
}
});
});
