hi everybody,

<script type="text/javascript">
<!--
    var image1 = new Image()
    image1.src = "test1.aspx?ImageID=?"
    var image2 = new Image()
    image2.src = "test2.aspx?ImageID=?"
    var image3 = new Image()

推荐答案

一种管理方式将JS插入到页面中后端C＃代码正在使用

RegisterClientScriptBlock ，参见示例：

One managed way to insert JS into the page while in the back-end C# code is using
RegisterClientScriptBlock, see example:

ClientScriptManager cs = Page.ClientScript;
String csname1 = "PopupScript";
String csname2 = "ButtonClickScript";
StringBuilder sb = new StringBuilder();
cstext2.Append("<script type=\"text/javascript\"> function DoClick() {");
sb.Append("Form1.Message.value='Text from client script.'} </");
sb.Append("script>");
cs.RegisterClientScriptBlock(cstype, csname2, sb.ToString(), false);

最好，

@ faizal，



如果我们在.aspx文件中添加一个JavaScript函数，它的代码就无法更改。正如Herbisaurus所建议的那样，您将javascript函数编写为字符串。您可以根据需要在运行时更改和编写它。一旦你完成了它的编写，你必须确保它被读取并作为JS函数执行。



为此，请使用RegisterClientScriptBlock并将字符串作为参数传递。



参考 http://msdn.microsoft.com/en-us/library/system.web.ui.clientscriptmanager.registerclientscriptblock.aspx 本文有关RegisterClientScriptBlock的更多详细信息

@faizal,

If we add a JavaScript function in .aspx file, it's code can not be changed. As suggested by Herbisaurus, you write your javascript function as a string. You have full liberty to change and write it at runtime as you want. Once you are done writing it, you have to make sure, it's read and executed as a JS function.

To do that, use RegisterClientScriptBlock and pass your string as a parameter.
