I have a button .it is bind the data from database.

For example it has 30buttons the values like 1,2,3.....30.

when a user select 4buttons means the values should be like this 25,27,24,22.

How this things can happen.

What I have tried:

I tried with a label but it shows only one value

The user click the next button means that button value only shown.

Why don't you use checkboxes? It seems more natural that way

you can use the jquery to get all the selected checkboxes and the associated values,

JavaScript

<pre>function getValueUsingClass(){
	/* declare an checkbox array */
	var chkArray = [];
	
	/* look for all checkboes that have a class 'chk' attached to it and check if it was checked */
	$(".chk:checked").each(function() {
		chkArray.push($(this).val());
	});
	
	/* we join the array separated by the comma */
	var selected;
	selected = chkArray.join(',') + ",";
	
	/* check if there is selected checkboxes, by default the length is 1 as it contains one single comma */
	if(selected.length > 1){
		alert("You have selected " + selected);	
	}else{
		alert("Please at least one of the checkbox");	
	}
}
