如何使用jQuery Dialog OK按钮调用函数？

Question

我试图从Jquery对话框Ok按钮调用一个函数.

我试过这两种方法,

1

this.commentDialog = function(){
        $("#commentDialog").dialog( "destroy" );
        html = "<div id='cmtDialog'>";
        html += "Comment<textarea id='comment'></textarea></div>";
        $("#commentDialog").html(html);
        $("#commentDialog").dialog({
            title:"Search Result",
            bgiframe: true,
            height: 'auto',
            width: 'auto',
            modal: true,autoOpen: true,
            buttons: { "Ok": function() { this.saveComment();}}
            });

2

this.commentDialog = function(){
        $("#commentDialog").dialog( "destroy" );
        html = "<div id='cmtDialog'>";
        html += "Comment<textarea id='comment'></textarea></div>";
        $("#commentDialog").html(html);
        $("#commentDialog").dialog({
            title:"Search Result",
            bgiframe: true,
            height: 'auto',
            width: 'auto',
            modal: true,autoOpen: true,
            buttons: { "Ok": function() { saveComment();}}
            });

两个都不工作!

我该如何用jquery做到!!

谢谢!!!

Answer 1

this.commentDialog = function(){
        // save a reference of "this" and use it later.
        var me = this;

        $("#commentDialog").dialog( "destroy" );
        html = "<div id='cmtDialog'>";
        html += "Comment<textarea id='comment'></textarea></div>";
        $("#commentDialog").html(html);
        $("#commentDialog").dialog({
            title:"Search Result",
            bgiframe: true,
            height: 'auto',
            width: 'auto',
            modal: true,autoOpen: true,
            buttons: { "Ok": function() { 
                 // use me instead of this, as this now refers to the function.
                 me.saveComment();}}
            });
