如何从C＃.net传递包含\\ n和\\ t的长文本的javascript参数

Question

I have a javascript function that has 5 parameters. I need to pass a large amount of text (it is a stack trace from C#.net code behind to the js function

Code :

function createDIV(CLASS_NAME, METHOD_NAME, APPLICATION_NAME, EXCEPTION_MESSAGE, STACK_TRACE_TEXT, EXCEPTION_OCCURANCE_STATUS) {   
    \\processing the code
}

When I call this function it works for all other values but if the text contains \\n it fails

sample text : org.apache.struts.chain.commands.InvalidPathException: No action config found for the specified url.\\n\\tat org.apache.struts.chain.commands.AbstractSelectAction.execute(AbstractSelectAction.java:68)\\n\\tat

Calling code:

ClientScript.RegisterStartupScript(
    GetType(), 
    "sss", 
    "createDIV(
        '" + CLASS_NAME.ToString() + "','" + METHOD_NAME.ToString() + "','" + 
            APPLICATION_NAME.ToString() + "','" + EXCEPTION_MESSAGE.ToString() + "','" + 
            STACK_TRACE.ToString() + "');",
true);

I'm also unable to replace the \\n with its html equivalent in C#.net. it just returns -1 for its occurance

Please help

Answer 1

尝试STACK_TRACE = STACK_TRACE.Replace(Environment.NewLine, "<br>");

Answer 2

In your C# code,for example:

string str = "TEXT TEXT TEXT\n, TEXT TEXT\t TEXT. TEXT TEXT\n\t TEXT TEXT.";
str = str.Replace("\n", "<br/>").Replace("\t", "<br/></br>");

Result:

**TEXT TEXT TEXT<br/>, TEXT TEXT<br/></br> TEXT. TEXT TEXT<br/><br/></br>TEXT TEXT.**

You can write series of replaces.

If you want to replace in javascript then use RegExp. See this article
