后台代码中如何调用前台JS函数?

Question

if(!IsPostBack)
{
    //语句,调用前台的JS函数;
}这语句要怎么写?

Answer 1

Page.RegisterStartupScript("Script","<script>alert('Hello World');</script>");

Answer 2

Response.Write("<script language=javascript>js函数名();</script>");

Answer 3

StringBuilder strBuilder = new StringBuilder();
    
strBuilder.Append("<script language='javascript' type='text/javascript' defer=defer >");
strBuilder.Append("函数名");
                    
strBuilder.Append("</script>");
                    
base.Page.ClientScript.RegisterStartupScript(this.GetType(), "RowColor", strBuilder.ToString());建议用StringBuilder去拼。。这样的话效率会高点。。

Answer 4

Page.RegisterStartupScript( "Script ", " <script> alert( 'Hello   World '); </script> ");
2.0被取消掉了~~肯定是因为效率或者安全吧~

Answer 5

1、Response.Write();
2、Page.ClientScript.RegisterStarupScript();
一般用后者 ，具体详细见MSDN

Answer 6

ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "", "javascript:alert('Test!')", true);
如果使用ajax

Answer 7

ClientScript.RegisterStartupScript(this.GetType(), "aa", "js函数", true);
