【正文】 a public Web site, you can not control other people using the browser, so Internet Explorer can only be used for clientside scripting this limitation is a problem. However, if you are in the browser known case of VBScript prepared using client script, it is feasible.If your target platform can support VBScript, consider the following factors to decide whether to use VBScript to write the script:Error control. In the VBScript On Error Resume Next to special cases are given to illustrate the. If you write is server script, error control is very important, because the script is unattended.Formatting. VBScript has such a function, can easily change data, numeric and currency data format.In the Internet Explorer event control is very convenient, just like in Visual Basic. In the VBScript also can create an implicit event handler, which only requires the use of object _ _ event structure to define a function on the line, for example Button1_onclick. However, in Internet Explorer, JScript cannot function ( but in other host JScript support this feature ).When selecting a JScriptAlmost all allow scripting browsers support JScript. Therefore, if you are a public Web site preparation of a widely distributed applications, use JScript to prepare the client script is natural selection. You will also find, because JScript application so widely ( and it is similar to JavaScript), is a standard scripting language, you can in the bookstore, the Internet can find lots of information about resources.If you want to use JScript to prepare a server script, then you should check your server does not support it. Microsoft IIS allows you to use the JScript to prepare ASP webpage script, but this is not all servers support.In the same webpage simultaneously use several languagesIn the same webpage can use different scripting languages. Why do you want to do this? Here are a few reasons:The first reason is: you just want in a program using a language advantage, and other parts of the script or to use another language to write.The second reason is: May you face your existing code is not familiar with the language to write. For example, the design of time control is prepared to use JScript, you are familiar with the language is VBScript. In most cases, you can be in the same webpage in a mixture of several scripting languages and between them can cooperate well. Using a language script can be invoked using another language to program and to share the global variables. But sometimes there will be a little problem, now I will explain it thereon.In a VBScript call in bracketsWhen you from the VBScript calls a JScript function, attention during the call to the brackets, even if this function is not required to set the parameters should be so. For example, a call should be like this:RetVal = callJSFunction ( )If you forget the bracketed, so the function of the returned value is not what you want, but contains a function oneself target.From VBScript to JScript transmitting arraySometimes a VBScript program will transmit an array as a parameter, or as its return value. You can see from the JScript call this procedure, but must have the VBScript array is converted into a usable JScript array. As long as you are in the JScript function to create a VBArray object and uses toArray to convert it into a JScript array can be.Note: JScript does not support a multidimensional array, if the original VBScript array is multidimensional, after toArray conversion after it will bee a onedimensional array of JScript.In the following example is a VBScript script, it established an array, and a JScript script, it will illustrate how to acquire and use the array: SCRIPT LANGUAGE = VBSCRIPT Function makeArrayVB.39。Creates a VBScript arrayDim anArray (1,1)AnArray (0,0) =0,0AnArray (0,1) =0,1AnArray (1,0) =1,0AnArray (1,1) =1,1MakeArrayVB = anArrayEnd Function SCRIPT LANGUAGE = JavaScript / / Accesses a VBScript array within a JScript scriptFunction getVBArray.Var arrayObj.Var jsArray.ArrayObj = makeArrayVB ( )。JsArray = VBArray ( arrayObj ) . ToArray ( )。Alert ( VBScript array length = + )。/ / Displays the contents of the arrayFor ( I = 1。 I = 。 I + + ) {Alert ( jsArray [ I1] )。}} / SCRIPT However, in the current VBScript, in turn, is unable to do so. You cannot put a JScript array is converted into VBScript array. If you encounter is a JScript program, to convert an array, you can choose some practices:JScript prepared with the calling programUsing VBScript to write JScript programIf possible, put the JScript array is converted to a different structure, such as converting a limit of the string, so VBScript can use. For example, you can use the toString function to an array into a ma delimited string, without restrictions. Thus, in VBScript you can use the Split function to divide it into different units. It is obvious that this method does not work in most of the time, but sometimes really effective.Update script languageVBScript and JScript are not immutable and frozen language. The two languages of the engine are regularly updated, add a few new features, solve the problems identified. Because the two languages are in fact as ActiveX ponents to the application, so whenever you update any controller, you can at the same time to update them. When you install a new language engine, any need to call the engine application when they run some script calls this new engine these engines including Internet Explorer or Visual InterDev.腳本語言VBScript 和JScript之間的區別結構是VBScript 和JScript之間最大的區別。VBScript 是Visual Basic的子集，如果你曾經用過Visual Basic或者Visual Basic for Applications (VBA)，你就會覺得非常熟悉。但是它們并不是完全相同的，因為VBScript是特意為在瀏覽器中進行工作而設計的，它不包括一些在腳本這個范圍以外的特性，如文件訪問和打印等等。而另一方面，JScript是從一組編程語言如C、C++、以及Java等之中脫離出來的。如果你曾經用過C或者是Java，那么JScript的結構對你來說將會非常熟悉。即便你不知道這些語言也沒有關系，JScript的結構一點也不難，它像C和Java一樣方便而沒有它們那么復雜。注意：不管怎樣，JScript和Java是完全不同的兩種語言。Java是一種對于網頁應用程
