Jquery announced that it does not support earlier ie versions.
It seems like the end of the world has come.
Actually nothing. It doesn't matter if you use the old version to continue providing support for IE.
It won't force update, it won't block applications, and it won't take you to court because of several API infringements.
Multiple jquery is not a problem. The conflict between jquery and prototype has long been a perfect solution.
Noconflict.
Pay attention to the usage.
For example:
<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
VaR V14 = $. noconflict ( True );
Window. $ = {V14: V14 };
})();
</ Script >
< Script Type = "Text/JavaScript" SRC = "Scripts/jquery-1.7.2.min.js" > </ Script >
< Script Type = "Text/JavaScript" >
( Function (){
VaR V17 = $. noconflict ( True );
Window. $. v17 = v17;
})();
</ Script >
< Script Type = "Text/JavaScript" >
// V14 code
( Function ($ ){
}) (Window. $. V14 );
// v17 Code
( function ($) {
}) (window. $. v17);
script >
</Head>
<Body>
</Body>
</Html>
In this way, all conflicts can be solved.
