This series of articles mainly concentrates on working with JavaScript arrays. We shall start with the basics of JavaScript arrays and finally conclude with complex object based arrays in JavaScript. You can reuse these scripts to inject into server side controls easily (especially in .NET and Java).
An in depth discussion of JavaScript Arrays - Working with two dimensional arrays (Page 3 of 5 )
In the above two sections, we only worked with single dimensional arrays (arrays with only one level of indexing). Now, we shall deal with two dimensional arrays (arrays with two levels of indexing).
Now, let us try to develop a simple script (JavaScript) to declare and work with two dimensional arrays. Have a look at the following code:
<html> <head> <metaname=vs_targetSchema content="http://schemas.microsoft.com/intellisense/ie5"> <scriptid="clientEventHandlersJS"language="javascript"> <!-- function Show() { var ITArray = new Array(2300, 3105, 2909, 4800); var ProductionArray = new Array(1800, 1940, 2470, 4350); var ResearchArray = new Array(900, 1200, 1923, 3810); var salaryArray = new Array(ITArray, ProductionArray, ResearchArray); for (var i = 0; i < salaryArray.length; i++) { for (var j = 0; j < salaryArray[i].length; j++) { document.write(salaryArray[i][j] + "\t"); } document.write("<br>") } } function ButtonShow_onclick() { Show(); } //--> </script> </head> <body> <formid="form1"> <inputtype="button"value="Show"id="ButtonShow" name="ButtonShow"onclick="return ButtonShow_onclick()"> </form> </body> </html>
Actually, within the above code, the “meta” tag is not necessary. As I developed the above code using Visual Studio.NET 2003 Enterprise Architect, it was automatically added to provide its full featured mechanisms. The explanation for the above code is discussed in the next section.
