Jquery multi-select drop-down list plug-in jquery multiselect function introduction and use_jquery

There is a need for multi-select, and I found this plug-in on the Internet: multiselect
https://github.com/ehynds/jquery-ui-multiselect-widget
There is an introduction to this plug-in on the csdn blog, and many children's shoes Everyone has asked this question, how to get the selected value? What a good question, because I also discovered this problem when watching the demo, haha!

Let’s briefly talk about this plug-in:
jquery-multiselect is based on the Jquery-ui component system.
So when using it, you must first import the js and css related to jquery-ui.

Code to call multiselect plug-in:

Copy code The code is as follows:

$(function(){
$("select").multiselect({
noneSelectedText: "==Please select==",
checkAllText: "Select all" ,
uncheckAllText: 'Unselect all',
selectedList:4
});
});

There are many parameters when calling multiselect, I think it is official The document is very detailed, students who know E-text can read it.
Okay, here is the question we are most concerned about, how to get the selected value?

The official documentation does not find a method to obtain the value of the selected item in the select control. I read its source code and it is version 1.14pre. Really not found.

But we can DIY this plug-in ourselves! Quite simply!
First declare a variable to record the selected value list. Take a screenshot:

Then we will find that there is an update method in the source code. This method is used to obtain the text of the user-selected item. , haha, so we thought of a simple DIY:

Then add a method in the code:

Copy code The code is as follows:

MyValues:function(){
return multiValues;
}

ok, the DIY of the plug-in is completed. The following is the call on the page:

Copy code The code is as follows:

function showValues() {
var valuestr = $("#sela").multiselect("MyValues");
alert(valuestr);
}

Yeah, OK!
