if (!($result = MysqL_query($query,$link))) {
   die("Invalid sql query: " . $query);
}

我有以下JQuery代码片段：

$.ajax({
        url: "....search.PHP",data: ...,async: false,//to trigger error alert

        success: function(xml) {
            ...
        },error: function(xml) {
            foundError = true;
        },dataType: "xml"
    });

if(foundError) {
        setProgress("Could not complete the search because an error was found",ProgressBar.ERROR);
}

是否有可能让die调用触发JQuery错误函数回调？如果没有,我怎么会触发呢？
