JScript built-in object Array element deletion method we know that JScript provides us with a built-in Array object Array. In addition to constructor, length, and prototype, the Array object also provides 13 methods by default: concat, join, pop, push, reverse, shift, slice, sort, splice, toLocaleString, toString, unshift, and valueOf, but the delete method is not provided. If you are familiar with

I want to learn about JScript Bug and memory management. I am not familiar with JScript Bug and memory management. So I have compiled this article and hope it can solve your learning problems. 1. JScript Bug The ECMAScript of IE implements JScript to seriously confuse the naming function expressions. Many people have

When TextStraem is implemented, the code used to identify the file encoding is VBS. However, in JScript, there are no functions such as ASC and binary data cannot be processed, therefore, a special method is required to obtain the encoding identifier of the file switch. At first, we used ASCII encoding to read text data and simulate binary data reading. However, we found that if the character encoding is greater than 127, we only get a value smaller t

The execution sequence of JScript and HREF in IE and firefox has not been written about the code for a long time. The main reason is that the recent work has been concentrated on demand analysis. without the feeling in reality, there is no motivation for writing. A question about the execution sequence of JScript is discussed. The sample code is as follows: A.htm Click Me! Click Me! SCRIPT Function func (s

Use the @ cc_on statement in Jscript to identify the IE browser and version code. For more information, see. Activation condition compilation is supported. @ Cc_on remarks @ Cc_on statement activates Conditional compilation in the script engine. We strongly recommend that you use the @ cc_on statement in comments so that browsers that do not support conditional compilation will accept your script as a valid Syntax: /* @ Cc_on */ // The remainder of th

The script implements file downloading. This is jscript. The script version vbscript was released before, And the principle is the same. Jscript version The Code is as follows: Var objArgs = WScript. Arguments;Var sGet = new ActiveXObject ("ADODB. Stream ");Var xGet = null;Try {XGet = new XMLHttpRequest ();} Catch (e ){Try {XGet = new ActiveXObject ("Msxml2.XMLHTTP ");} Catch (ex ){Try {XGet = new Acti

above is the basic theory, and the following is the code. I found out when I studied jswiki and sorted it out. /**//** * Create a constructor with Singleton pattern, maintains only one single instance * @ Param _ Constructor */ Function $ Singleton (_ constructor )...{ VaR instance = NULL; Return function ()...{ Return (instance! = NULL )? Instance: (instance = new _ Constructor ()); } } The following is an example of an application (note that this is the
