对于条件，仅在调用JS File时运行一次 [英] For condition running only once when calling JS File

问题描述

我正在从c#代码运行Javascript.

I am running a Javascript from c# code.

  for(int i=0;i<=2;i++)
   {
        Page.ClientScript.RegisterStartupScript(GetType(), "a", "foo("hello")", true);
   }

Js文件

Function foo(a){
alert(a);
//some other logic
}

这里，问题是当我调试代码时，我可以看到循环进行了3次，但警报仅出现一次.

Here, the problem is when i debug the code, i can see loop going for 3 times, but the alert appears only once.

为什么只出现一次?我该如何解决?

Why does it appear only once ? How can I solve this ?

推荐答案

@Lloyd所说的是正确的，+ i是形成唯一对的必要条件.

What @Lloyd said is correct, the + i is necessary to make unique pairs.

尝试一下:

for (int i = 0; i <= 2; i++)
{
    Page.ClientScript.RegisterStartupScript(GetType(), "a"+ i, "foo('hello');", true);
}

您在javascript函数末尾缺少分号.

You were missing the semicolon at the end of the javascript function.

这就是@Lloyd建议产生的结果

This is what was being generated with what @Lloyd suggested

<script type="text/javascript">
//<![CDATA[
foo("hello")foo("hello")foo("hello")//]]>
</script>

这就是您想要的:

<script type="text/javascript">
//<![CDATA[
foo('hello');foo('hello');foo('hello');//]]>
</script>
</form>
