d_IV中的未定义文本 [英] Undefind text in d_IV

问题描述

在我的项目中，出现以下错误.我正在使用此代码在我的项目中显示菜单.

d_iv.text未定义.

以下是供您参考的代码:

Hi,

In my project I am getting the following error. I am using this code to display the menu in my project.

d_iv.text is undefined.

Here is the code for your reference:

var d_iv=_dmvi(id);
var d_lv=0;
while(d_iv.text.charAt(0)=="|")
{
d_lv++;d_iv.text=d_iv.text.substring(1);
}

预先感谢

Thanks in advance

推荐答案

好，很明显，无论dmvi(id)是什么，它都没有text属性.这就是错误的意思.您是否尝试过进行调试?警报(d_iv)找出它是怎么回事?

Well, it''s clear that whatever dmvi(id) is, it does not have a text property. That''s what the error means. Did you try doing some debugging ? How about alert(d_iv) to find out what it is ?
