I might not know what to call this, but essentially I want to pass the name of the property dynamically and then get the value of that property within my objects data property. Something like this:
function myFunc(e, myProperty) {
alert( e.data[myProperty] );
}
var myValue = myFunc(myObject, "someField");
I get the value undefined .
I think the equivalent in ColdFusion would be something[myPropertyName] and I'm wondering if there is something similar in JavaScript.
UPDATE: Apparently getting the value works, but not where I'm trying to pass the dynamic property as a name/value pair to an AJAX request.
var myValue = e.data[myProperty];
var myData = { myProperty: myValue }
In the code above myProperty is being passed as "myProperty"
Please try:
var myValue = e.data[myProperty];
var myData = { };
myData[myProperty] = myValue;
That should allow you to dynamically create an object with property named myProperty
worked for me:
function myFunc(e, myProperty) {
alert( e.data[myProperty] );
}
myObject = { data: {} };
myObject.data['someField'] = 123;
var myValue = myFunc(myObject, "someField");
