无法调用javascript函数 [英] Unable to call javascript function

问题描述

我在for循环中有一个javascript函数。我从代码隐藏文件中调用此函数。但即使循环有两次迭代，该函数也只被调用一次。这是代码。

Hi,
I have a javascript function in a for loop. i call this function from code behind file. but the function is only called once even if loop has two iterations. here is the code.

 for (int i = 0; i < nodes; i++)
 {
ClientScript.RegisterStartupScript(Page.GetType(), "abc", "func('" + xPosition + "','" + yPosition + "','"+nodes+"');", true);

 }

功能：

Function:

function func(xPosition, yPosition, nodes)
     {
         alert(nodes);
             svg = document.createElementNS('http://www.w3.org/2000/svg', 'svg');
             //            svg.setAttribute('xmlns:xlink', 'http://www.w3.org/1999/xlink');
             //            svg.setAttribute('version', '1.1');
             svg.setAttribute('width', '4cm');
             svg.setAttribute('height', '2cm');
             svg.setAttribute('x', xPosition);
             svg.setAttribute('y', yPosition);
             mainSvg.appendChild(svg);
             //alert(xPosition + '","' + yPosition);


             rect = document.createElementNS('http://www.w3.org/2000/svg', 'rect');
             rect.setAttribute("id", "myrect");
             rect.setAttribute("fill", "red");
             rect.setAttribute("stroke", "black");
             rect.setAttribute("stroke-width", "2");
             rect.setAttribute("x", 5);
             rect.setAttribute("y", 5);
             rect.setAttribute("width", "150");
             rect.setAttribute("height", "50");
             document.body.appendChild(rect);
             svg.appendChild(rect);


     }

推荐答案

你不能多次注册相同的类型/组合键。通过设置不同的键，您可以多次使用RegisterStatupScript

You can''t registering the same type/key combination more than once. By setting different key you can able to use RegisterStatupScript more than once

Hello Osama，



您遇到严重问题含有以下内容的行：

Hello Osama,

You have a serious problem with the line containing this:

func('" + xPosition + "','" + yPosition + "','"+nodes+"')

您正在尝试注册同样的功能很多次，当然是不允许的。



干杯，

Edo

You are trying to register the same function many times, which of course is not allowed.

Cheers,
Edo
