JQuery检查是否需要inout(JQuery check if the inout is required or not)

JQuery检查是否需要inout(JQuery check if the inout is required or not)

在我的HTML模板中，我需要为特定输入设置为False。

<div class="col-xs-2"> <input type="text" required="false" class="product-data form-control" id="description" placeholder="Description" name="description"/> </div>

我想打印JQuery中所需的值。

console.log("Value - " + $(this).attr("required"));

输出：

价值 - 必需

我希望它打印假。 有没有办法做到这一点。

In my HTML template, I have required set to False for a specific input.

<div class="col-xs-2"> <input type="text" required="false" class="product-data form-control" id="description" placeholder="Description" name="description"/> </div>

I want to print the value of required in JQuery.

console.log("Value - " + $(this).attr("required"));

Output :

Value - required

I want it to print false. Is there any way to do this.

最满意答案

尝试使用getAttribute() ：

document.getElementById('description').getAttribute('required')

希望这可以帮助。

console.log("Value - " + document.getElementById('description').getAttribute('required')); 
  
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-xs-2">
    <input type="text" required="false" class="product-data form-control" id="description" placeholder="Description" name="description"/>
</div> 
  
 
Try to use getAttribute() :
 
document.getElementById('description').getAttribute('required')
 
Hope this helps.
