how to loop through an array of unknown size

Hi,

I trying to write a code for iterating through the array.

Array size will be dynamic, that means we don't know how many elements are there internally.

So how can I create an array without size.

And my array will be a string.

 

var membernames=new Array();

Can I initialize this way?

I want to loop through a set of elements whose size is unknown and retrieve all those details into a variable.

How can I do this? Please let me know..

 

Thanks

I'm not sure what you're asking. Do you want to know how to iterate through an unspecified array size at runtime? If so, you can use push to add to an array, and use the length property to use as the ending conditional for a for loop.

 

You can find this info in the Array references sections

All arrays in Javascript have a length property which indicates how many elements they contain. If it doesn't have a length property then it's not an array.
