jquery set tabindex and cursor
提问by ShaneKm
I have the following code that assigns tabindex to my form id "register1". I would like to place the cursor on the first input or select list item on the form (item with tabindex = 1) once tabindexes are assigned. but the following line: $('#register1').find('input').attr('tabindex',1).select();Resets tabindex of all the inputs.
我有以下代码将 tabindex 分配给我的表单 ID“register1”。一旦分配了 tabindexes，我想将光标放在表单上的第一个输入或选择列表项（tabindex = 1 的项）上。但是下面这行：$('#register1').find('input').attr('tabindex',1).select();重置所有输入的 tabindex。
Full code:
完整代码：
$(function(){
var tabindex = 1;
$('#register1').find('input,select').each(function() {
if (this.type != "hidden") {
var $input = $(this);
$input.attr("tabindex", tabindex);
tabindex++;
}
});
$('#register1').find('input').attr('tabindex',1).select();
});
thanks
谢谢

Simply select the item with tabindex one in your loop using a condition:
只需使用条件在循环中选择带有 tabindex 的项目：
$(function(){
var tabindex = 1;
$('#register1').find('input,select').each(function() {
if (this.type != "hidden") {
var $input = $(this);
$input.attr("tabindex", tabindex);
// select the first one.
if (tabindex == 1) {
$input.select();
}
tabindex++;
}
});
});
