具有多个提交按钮的表单，如何设置默认的输入键操作-条形码扫描器输入

Question

I've been stuck on this issue. I have a simple form:

<form>
<input type="text" name="barcode1">
<input type="submit" name="barcode1" value="Submit Barcode1">
<input type="text" name="barcode2">
<input type="submit" name="barcode2" value="Submit Barcode2">
</form>

I'm using a barcode scanner to enter the data into the text field. The scanner records a series of numbers, followed by a 'Enter' command.

When I scan into the barcode1 field, it works perfectly, the form is submitted by the scanner's 'Enter' command.

When I scan into barcode2 field, it submits the form using the barcode1 submit.

Is it possible, to change the default submit button on a form with multiple submit buttons? Perhaps I could set the default submit button when I focus on the text field for that submit button.

Answer 1

Something like this?

$(document).ready(function() {
    var toClick;
    $(":text").focus(function() {
        toClick = $(this);
    });
    $('form').keypress(function(event) {
        if (event.keyCode == 13) {
            event.preventDefault();
            $(toClick).next('input[type="submit"]').click();
        }
    });

});
