jquery method to get Select selected value Analysis _jquery

The example in this article describes jquery's approach to getting select selected values. Share to everyone for your reference, specific as follows:

Misunderstanding:

I used to think that jquery gets the text value that option is selected in the Select, which is written like this:

Copy Code code as follows:

$ ("#s"). Text (); Get text values for all option

This should actually happen:

Copy Code code as follows:

$ ("#s option:selected"). Text (); Gets the text value of the selected option

Gets the selected value value of option in the Select:

$ ("#s"). Val ();
$ ("#s option:selected"). Val ();

JS Gets the value selected by select:

var Sel=document.getelementbyid ("Select1");
var index = Sel.selectedindex; Select
the value of the index albumid= sel.options[index].value;//

I hope this article will help you with the jquery program design.
