jquery or css selector? select all id’s that start with

This code changes #idview‘s src attribute on mouse-over of ids 1-3.

$("#id_1, #id_2, #id_3, #etc").mouseover(function(){
    $("#idview").attr("src","id_" + this.id.substr(3,4) + ".jpg");
});

How can I select an ID by “#id_” and then a variable integer? Say for example if there were 1000 images, where it would be impractical to write this out long hand?

It may be something like $("#id_"+*)?

Answer 1

Use an attribute starts-with selector:

$("[id^='id_']").mouseover(function () {
    //Do stuff
});

It would be a little more efficient to clarify the element type before the attribute selector, but it’s not clear from your question exactly what elements you’re trying to select.
