This article introduces the "ASP.NET commonly used to output JS scripts class method tutorial" related knowledge, in the actual case of the operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

The details are as follows:

Very often in ASP.NET, we often need to output some JS scripts, such as a pop-up warning window, return to the history page and other JS functions. I see that what is widely spread on the Internet is a JScript class written by Ma Xianguang, which basically contains the frequently used JS script, which is very convenient. The only deficiency is the Response.Write (string msg) method adopted by the author, which results in the output js script outside the tag. Destroy the structure of the original XHTML, so I made further improvements to the JScript class to meet the original function. This improvement adopts the method of overloading and adds an instance of the System.Web.UI.Page class as a parameter, which will not affect the original program code.

The code of the whole program is as follows:

The copy code is as follows:

Using System

Using System.Collections.Generic

Using System.Text

Using System.Web

Using System.Web.UI

/ / /

/ / some commonly used Js calls

/ add a new version of note: because the old version generally uses Response.Write (string msg) to output js scripts, this

The js script output in the / mode destroys the structure of the entire xhtml outside the tag of the html element

/ / the new version is outputted by ClientScript.RegisterStartupScript (string msg), which will not change the structure of xhtml

/ / will not affect the execution effect.

/ / for backward compatibility, the new version is overloaded and requires an instance of the System.Web.UI.Page class.
