如何将JQuery变量值分配给Laravel Blade输入

I have a variable(string) called "cost". If I attempt to assign it to a

我有一个名为“cost”的变量(字符串)。如果我尝试将其分配给

<p class="cost"> </p>

it works fine. However when I attempt to assigned it to Blade generated "readonly" input I get nothing. I get no output of the "cost" value in the input field. I have tried unescaping the BLade input, also tried raw JS.

它工作正常。但是,当我尝试将其分配给Blade生成的“readonly”输入时,我什么也得不到。我在输入字段中没有输出“cost”值。我试过unescaping BLade输入,也试过原始的JS。

  $(".quantity").on('change', function(){
    var quantity = parseInt($(this).val());
    var num = (price * quantity);
    var cost = num.toString();
    $('.cost').html(cost);  // This will not assign the value ! 
});

Blade Input:

<div class="col-sm-2 col-md-2">{!! Form::text('cost[0]', null ,['class'=>'form-control cost', 'readonly'=>'readonly' ]) !!}</div>

The source code Blade produces looks like this:

Blade生成的源代码如下所示:

<div class="col-sm-2 col-md-2"><input class="form-control cost" readonly="readonly" name="cost[0]" type="text" value=""></div>

You aren't using class="cost" on input you are using id="input" so selector needs to be changed.

您在使用id =“input”的输入上没有使用class =“cost”,因此需要更改选择器。

In addition you set value not html on inputs

另外,您在输入上设置值而不是html

Try

$('#cost').val(cost);
