Here's the fiddle
https://jsfiddle.net/46o8bvcu/1/
$(".chosen").chosen().change(function(e, params){
var id = $(this).val();
alert(id);
});
It returns the value on add option but throws undefined/null/blank when removing option.How can I get the value of the item which was removed?
$(this)
inside the change method refers to the <select></select>
element.
The .change()
method also sends selected and deselected parameter to tell which option was changed. As per the docs here.
Change Event: Chosen triggers the standard DOM event whenever a selection is made (it also sends a selected or deselected parameter that tells you which option was changed).
Something like this should tell you which option was selected and which option was deselected.
$(".chosen").chosen().change(function(e, params){
if(params.deselected){
alert("deselected: " + params.deselected);
}else{
alert("selected: " + params.selected);
}
});
Here is a demo https://jsfiddle.net/dhirajbodicherla/46o8bvcu/2/
$(".chosen").chosen().change(function(e, params) {
if (params.deselected) alert("deselected: " + params.deselected);
else alert("selected: " + params.selected);
});
