  1. PORecursive function to serialize a javascript object for an ajax request - is there an easier way?
    text
    copied!<p>Here is a function and helper that I wrote to serialize a javascript object for sending in an ajax request. Chances are there is a more efficient solution out there somewhere, probably in the jQuery library, but I can't find one. Not one for a javascript object.</p> <pre><code>/* @author Benjamin Yep @important - THIS FUNCTION ASSUMES INPUT ENCODED ACCORDING RFC 3986 see here: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURIComponent @param data - Any javascript object or array. @param pName - The name of the object to be sent in your ajax request. @return A serialized JSON-encoded object, ready to send in a request. Usage: var someObject={ "foo":"bar", "bars":["foo","bar"], "object":{ "foo":1, "bar":2", }, }; var r=makeHttpObject();//new ajax object r.open("get","example.php",false); r.send(paramify(someObject,"varname")); //In example.php &lt;?php echo var_dump($_POST['varname']); ?&gt; //back in the javascript file console.log(r.responseText);//shows the contents of the object you sent to the server */ function paramify(data,pName){ return constructObject(data,pName).substr(1); } function constructObject(data,path){ var contents=""; for(var key in data){ var curpath=path+"["+key+"]"; if(Object.prototype.toString.call(data[key])==='[object Object]'||data[key] instanceof Array){ if(!(data[key] instanceof Array)||data[key].length!=0){ if(JSON.stringify(data[key])=="{}"){ contents+="&amp;"+curpath+"={}"; }else{ contents+=constructObject(data[key],curpath); } }else{ contents+="&amp;"+curpath+"=[]"; } } else{ contents+="&amp;"+curpath+"="+data[key]; } } return contents; } </code></pre>
