Question

如何将下面的两个脚本合并为一个，目标是让脚本为表单中的输入/选择字段生成tabindex顺序功能（其中1,7,3是字段的ID（＃））？

$(function(){
var tabindex = 1;
$('input,select').each(function() {
    if (this.type != "hidden") {
        var $input = $(this);
        $input.attr("tabindex", tabindex);
        tabindex++;
    }
});
});


$(function () {
var tab_order_positions = [1, 7, 3],
tab_order = 0;
for (var i = 0, _len = tab_order_positions.length; i < _len; i++) {
    $('#input_' + tab_order_positions[i]).attr('tabindex', ++tab_order);
}
});
