jQuery循环创建元素 [英] jquery loop to create elements

问题描述

到目前为止，我对这个任务还没有运气，因此非常感谢您的帮助.

I have had no luck with this task so far so grateful for any help.

我有一个html表单，其中有一个小的选择菜单(1-10) 即

I have an html form, in which there is a small select menu (1-10) ie

<select>
    <option value = '1'>1</option>
    <option value = '2'>2</option>
    ...
    <option value = '10'>10</option>
</select>

根据选择的值，我希望jquery创建(或删除)一定数量的输入文本框(具有不同的名称和ID). 例如，如果选择2，则将创建以下输入:

depending on what value is selected i would like jquery to create (or remove) that number of input text boxes (with different names and id's). eg if 2 was selected these inputs would be created:

<input type = 'text' name = 'name1' id = 'id1' />
<input type = 'text' name = 'name2' id = 'id2' />

毫无疑问，我期待您简单而优雅的解决方案！ 安迪

i look forward to your no doubt simple and elegant solutions! andy

推荐答案

类似以下内容:

$('select').change(function() {
     var num = parseInt($(this).val(), 10);
     var container = $('<div />');
     for(var i = 1; i <= num; i++) {
         container.append('<input id="id'+i+'" name="name'+i+'" />');
     }
     $('somewhere').html(container);
});
