jQuery Select2动态添加带有变量定义“ val”的项目

Question

I am using jquery select2 and manually works fine! However, I want to dynamically add items by using this piece of code that I found in that project's github page :

$("#e13").val("CA").trigger("change"); //works!

The above example works fine. But when I try to substitute "CA" with an equal variable it does not work:

var california = "CA";
$("#e13").val('"'+california+'"').trigger("change");// does not work

I have also prepared a FIDDLE

Thanks to TSmith and fernandosavio suggestion, single value worked. My actual goal though is a variable with multiple values:

var combo = "FL,CO,AZ";
var array = combo.split(",");
$("#e13").val(['"'+array+'"']).trigger("change"); //does not work
//$("#e13").val(["FL","CO","AZ"]).trigger("change"); //this WORKS!

That is also included in the above fiddle...

Any advice?

Answer 1

您不需要做所有的引号和加号操作：

$("#e13").val(california).trigger("change");

Answer 2

@TSmith is right.

JS Fiddle your fiddle updated.

california is already a string

$("#e13").val(california).trigger("change");

and array is already an array

$("#e13").val(array).trigger("change");

So, no need to put quotes on it.
