jquery/javascript concat question

Question

I want to create a jQuery statement that looks like this:

$('.total_999').html("something");

However, 999 comes from variable called storeNo .

How can I construct this statement dynamically?

Answer 1

$（+ storeNo '总_。'）。html的（ “东西”）;

Answer 2

total_999 in your example is a class. Since it appears to be unique (or likely so), then it should probably be the id, and use a more generic class.

for example:

<div id="total_999" class="total">...</div>

then you can use the id, or the class to refer to the element

$('#total_'+storeNo); //get the element

or

$('.total'); //get all of the totals

A more complete example might be:

function setTotal(storeNo, total) {
  $('#total_'+storeNo).html(total);
}

setTotal(999,'$1,276');
