JQuery SELECT radio simulation jQuery.select.js_jquery

Single selection simulation based on jQuery JavaScript Library v1.3.2
(This file is modified based on zhangjingwei’s Jquery Select (radio selection) simulation plug-in V1.3.4)
a. The main reason for the modification is that the original Zhangjingwei's simulation has a problem with the display method. There will be misalignment when appearing alternately with text. Now change the display of the simulated DIV to inline mode. More naturally embedded into lines of text.
b. Automatically convert the select style named 'commonselect' after loading the file. Simplify the call
c. Response to the onchange() event of select. And small adjustments to width acquisition
