Question

将输入中的数据发送到custom.js，并根据custom.js文件中的输入进行计算，并从custom.js中将总和值发送到create.blade.js

create.blade.php

<div class="form-group col-md-4">                           
<label for="amount_received">Amount Received</label>
<input type="text" class="form-control" name="p_amount_received" 
id="p_amount_received" oninput="myfunction()" placeholder="Enter Amount 
Received" required="">  
</div>

通过id获取在custom.js中接收的p_amount _

custom.js

function myFunction() {
  var x = document.getElementById("p_amount.received").value;
  var sum=x+10;
}

create.blade.php

我如何在

create.blade.php

中取回总和

Answer 1

您可以使用标头中的脚本标签或create.blade.php中的类似内容加载custom.js，甚至可以使用onchange调用myFunction，

<input type="text" class="form-control" name="p_amount_received" 
id="p_amount_received" onChange="myFunction()" placeholder="Enter Amount 
Received" required="">
<label id='p_sum_display'>Sum</label>
<input type="hidden"  name="p_sum" id="p_sum" >

创建sum作为输入以提交给服务器，并sum作为显示标签以进行ui显示，并通过myFunction之类的方法填充值，

function myFunction() {
  var x = document.getElementById("p_amount_received").value;
  var sum=x+10;
  document.getElementById("p_sum").value = sum  //for submit to server
  document.getElementById("p_sum_display").innerHTML = sum // to display to user on ui
}
