JAVASCRIPT中UTF8页面提交数据乱码怎么办

if(isIE && document.charset!=”utf-8″){
document.charset=’utf-8′;
location.reload(false);}

var isIE=!!window.ActiveXObject;
if(isIE && document.charset!=”utf-8″){
document.charset=’utf-8′;
location.reload(false);}

ajax: function( origSettings ) {
    var s = jQuery.extend(true, {}, jQuery.ajaxSettings, origSettings);
   
    // ............... 去掉一些无关的代码

    // convert data if not already a string
    if (s.data && s.processData && typeof s.data !== "string") {
        // 注意下面这个调用
        s.data = jQuery.param( s.data, s.traditional );
    }

// Serialize an array of form elements or a set of
// key/values into a query string
param: function( a, traditional ) {
    var s = [];
    // ............... 去掉一些无关的代码
   
    // If an array was passed in, assume that it is an array of form elements.
    if ( jQuery.isArray(a) || a.jquery ) {
        // Serialize the form elements
        jQuery.each( a, function() {
            add( this.name, this.value );
        });
       
    } else {
        // ............... 去掉一些非重点代码
    }

    // Return the resulting serialization
    return s.join("&").replace(r20, "+");

    function add( key, value ) {
        // If value is a function, invoke it and return its value
        value = jQuery.isFunction(value) ? value() : value;
        s[ s.length ] = encodeURIComponent(key) + "=" + encodeURIComponent(value);
    }
}
