Please help and thanks in advance....

这是一个语法错误。因为你在这里错过了一个紧密的大括号''''':
It''s a syntacticle error. Since you missed a close braces '')'' here:
html+="<div>" + GetDynamicTextBox*(values[i] + "<div>";
用以下内容替换该行:
Replace the line with following:
html+="<div>" + GetDynamicTextBox*(values[i] + "<div>");
还有onload你打电话 window.onload = RecreateDynamicTextBoxes;
而你的函数名是 RecreateDynamicTextBox
--Amit
And also onload you are calling window.onload=RecreateDynamicTextBoxes;
whereas your function name is RecreateDynamicTextBox
--Amit
我认为,在onClick事件中你调用了
I think, in onClick event you have called
onclick="Button2_Click1"
但是没有相同的定义。
所以通过将onClick事件更改为
but there is no definition for the same.
So by changing the onClick event to
onclick="Button2_Click"
可能适合你。
