不区分大小写的jQuery:包含选择器

Posted 2021-02-25

This will extend jquery to have a :Contains selector that is case insensitive, the :contains selector remains unchanged.

// For jQuery 1.2
 
jQuery.extend(
    jQuery.expr[':'], { 
        Contains : "jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())>=0" 
});
 
 
// For jQuery 1.3 (thanks @user95227) and later you need
 
jQuery.expr[':'].Contains = function(a,i,m){
     return jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase())>=0;
};
