Question

I have written following code in html:

<input type="text" id="id_1" name="text_1">
<input type="text" id="id_2" name="text_2">
<input type="text" id="id_3" name="text_3">

Here I have to get all textBoxes in an array in javascript function whose id starts with “id”. So, that I can get above two textBoxes in an array.

How to get all textBoxes whose id start with “id”?

Answer 1

var ele = document.getElementsByTagName("input");
var matchingEle = [];
var eleName = '';

for (var i = 0; i < ele.length; ++i) {
 el = ele[i];
 eleName = el.getAttribute("name");
 if (eleName && eleName.indexOf("text_") == 0) {
     matchingEle.push(el);
 }
}
