本文实例讲述了jQuery实现contains方法不区分大小写的方法。分享给大家供大家参考。具体实现方法如下:

// NEW selector  
jQuery.expr[':'].Contains = function(a, i, m){
 return jQuery(a).text().toUpperCase()
   .indexOf(m[3].toUpperCase()) >= 0;
};  
 
// OVERWRITES old selecor
jQuery.expr[':'].contains = function(a, i, m){
 return jQuery(a).text().toUpperCase()
   .indexOf(m[3].toUpperCase()) >= 0;
};

用法:

$("div:contains('John')")

测试HTML文件:

<div>john</div>
<div>John</div>
<div>hey hey JOHN hey hey</div>

希望本文所述对大家的jQuery程序设计有所帮助。
