Say I have a bunch of names in a array and I want to post this data to another url on my site, but the post data will be "name="+name+"&name="+name+""; etcetc
So for each name i need to generate another name= to add to post data until there are no more names
How can I do this?
You can map every element in the array to the same thing with name= prepended, and then join them with the & character.
return names.map(function(name) {
return "name=" + name;
}).join("&");
If you need to support browsers that don't have the map method on Array (it requires JS 1.6), you can pinch it from the MDC or just use a for loop instead.
var queryBits = [];
for (var i = 0, len = names.length; i < len; i++) {
queryBits.push("name=" + names[i]);
}
return queryBits.join("&");
map is not available in all browsers... edit: +1 for a more complete solution
escape function to make sure there are no dodgy characters in your query string: return "name=" + escape(name);.You can use jquery param() to serialize an array to post it in a url. look here for reference. It's very useful becouse it encodes automatically your data.
