jQuery选择器在字段集中查找输入 [英] Jquery selector finding input inside fieldset

问题描述

我喜欢在字段集中查找输入框的值，如下所示

I like to find value of an input box which is inside a fieldset as follows

fieldset> div >div> input[with class name 'inputclassname']

我知道字段集的ID，并尝试使用其类名查找输入的值，但是我无法确定.value是未定义的.

I know the id of fieldset and trying to find value of input with its class name but I am not able to .value is undefined.

我这样尝试过

$('#ID of fieldset').find($('.inputclassname')).val();

它总是返回未定义状态.有什么建议吗?

it always returning as undefined. Any suggestions?

推荐答案

<fieldset id="fs">
    <div>
        <div> 
            <input class="someclass" value="hey" />
        </div>
    </div>
</fieldset>
<script type="text/javascript" charset="utf-8">
    alert($("#fs input.someclass").val())
</script>
