[英]Pass a value to a Javascript function from C# code behind
I have this javascript function in a .aspx file. 我在.aspx文件中有此javascript函数。
<script>
function somefun(value)
{
}
<script>
I'm calling and passing a value to that function inside the code-behind class. 我在代码隐藏类内调用该函数并将值传递给该函数。
ScriptManager.RegisterStartupScript(this, typeof(string), "Passing", String.Format("somefun('{0}');", filePath1), false);
But when it runs, the function doesn't work properly. 但是,当它运行时,该功能无法正常工作。 I'm getting an printed output like this 我得到这样的打印输出
" somefun(the content of the variable) " “ somefun(变量的内容) ”
What would be the issue? 会是什么问题?
Try with: 尝试:
ScriptManager.RegisterStartupScript(this, typeof(Page), "Passing", String.Format("somefun('{0}');", filePath1), false);

First, I like to use a function to Execute Javascript code on the client browser... 首先,我喜欢使用一个函数在客户端浏览器上执行Javascript代码...
#region ExecuteJavascript
private int _intScriptIndex = 0;
private void ExecuteJavascript(string strScript)
{
System.Web.UI.ScriptManager.RegisterStartupScript(Page, typeof(Page), "ExecuteScript" + _intScriptIndex++, strScript, true);
}
#endregion
Now I just call JavaScript like this... 现在,我像这样调用JavaScript ...
ExecuteJavascript("alert('test');");
To call a function with variables you would do this... 要使用变量调用函数,您可以执行此操作...
ExecuteJavascript(String.Format("somefun('{0}');", filePath1));
That should do it. 那应该做。 The key to why mine works and yours doesn't is probably in the properties of RegisterStartupScript, notice that I pass Page and typeof(Page) where you put string. 我的工作原理和我的工作原理不起作用的关键可能在于RegisterStartupScript的属性,请注意,我在放置字符串的地方传递了Page和typeof(Page)。
请尝试这个
ScriptManager.RegisterStartupScript(this, typeof(string), "Passing", "somefun('" + filePath1 + "');" ,false);
This should work. 这应该工作。
C# code: C#代码:
String vls_variable = "TestData";
ScriptManager.RegisterStartupScript(this, typeof(string), "script1", "SampleJSFunction('" + vls_variable + "');", true);
JavaScript function: JavaScript函数:
function SampleJSFunction(variable)
{
var data = variable;
alert("working");
}
