Ever wanted a getJSON which does a post?
Here it is:
jQuery.extend({
postJSON: function(url, data, callback)
{
$.post(url, data, callback, "json");
}
});
jQuery getJSON POST

jQuery submit button and button named submit
Suppose you have a button named "submit":
<form method="post" action="" id="myForm"> <fieldset> <input type="text" name="myField" /> <input type="submit" name="submit" value="submit form" /> </fieldset> </form>
And you want to submit this form with jQuery:
<script type="text/javascript"> SomeFunction() { $("#myForm").submit(); } </script>
That won’t work since you have a button named ‘submit’ which then screws up the jQuery function. If you rename it to ‘submitForm’ or something it will work fine.
Javascript: foreach
Die er niet is 
Er is dus geen foreach in Javascript. Jammer want dit geeft meer obvious code:
String[] listNames = listViewNames.GetNames();
for(int x = 0; x < listNames.length; x++)
{
String name = listNames[i];
//do something with name
}
wordt...
String[] listNames = listViewNames.GetNames();
foreach(String name in listNames)
{
//do something with name
}
Er is wel een andere syntax voor het for statement, wat lijkt op foreach
var listnames = listViewNames.GetNames();
for(var index in listNames)
{
//i is now the index
var name = listNames[index];
//do something with name
}
Een extra stap dus, maar het kan handig zijn
