spring mvc 3 populate javascript var from property file

问题

I need to populate a JavaScript variable with a property value (that defined in a property file) when page get loaded . i am using spring mvc 3. is there any best way to do it? appreciate if someone give me some clue.

Thanks in advance.

回答1:

• Create an initializer method in the javascript file
• output the properties in the page that includes the js. so that they form a valid javascript structure (array, object, whatever)
• pass the structure to the initializer.

The 1st step may look like (in the .js file):

var options;
function init(initOptions) {
   options = initOptions;
}

The 2nd step may look like (in your jsp page):

var a = new Array();
<c:forEach items="${properties}" var="entry">
   a.push({key: '${entry.key}', value: '${entry.value}'});
</c:forEach>

And finally init(a);
