用jQuery更改div ID

Question

I have a bit of code that lets me drag and drop elements. The problem is that i don't know how to change the id of the element when it's dropped. It needs to stay a list with the right numbers.

<div class="container">     

    <div class="block">
        <div id="draggables">
            <div id="dragbox1" class="stepbox">
                <label>Step 1</label>
                <input type='text' placeholder="Omschrijving" name="textbox1">
            </div>
            <div id="dragbox2" class="stepbox">
                <label>Step 2</label>
                <input type='text' placeholder="Omschrijving" name="textbox2">
            </div>
            <div id="dragbox3" class="stepbox">
                <label>Step 3</label>
                <input type='text' placeholder="Omschrijving" name="textbox3">
            </div>
        </div>
    </div>

</div>

When i drag a div (for example the div with id dragbox1 down under the div with id dragbox3) i want the jquery to rename the div id's so that it stays in the same order from 1,2,3 and not 2,3,1.

I'm thinking it should be sometging like the folowing:

var divClass = /*div class name*/;
var divId = /*static div id name*/;

var checkDivOrder = function(){
        if(/*check for divs with the name of the divClass*/) {
            if (divId === /*static div id name*/) {
            divId = /*divIdName*/ + 1;
        } else {
            divId = /*divIdName*/ + /*previous div id number*/ + 1;
        }
    }
};

//recall function
if(/*div being dropped*/){
    checkDivOrder(/*prev div number + 1*/);
}

Could someone help me with this as my jquery and javascript skills are not that great.

According to my understanding you want you div in order top to down like dragbox1,dragbox2,dragbox3 in sequence.

you can do like this.

  $('.stepbox').each(function(ind,obj){ $(this).prop('id','dragbox'+(ind+1)); });
