Json数据计算和html

Question

I'm new to Javascript. In fact it has a very simple answer but I can't :(

Price display javascript code;

 $('#totalPricefark').html(data.totalPrice);

Html

<strong id="totalPricefark">0</strong>

What I want to do;

data.totalPrice * 0.6 calculation and show in #totalPricefark

Thanks

Answer 1

This takes the value from the priceFark div, parses it into an integer via pareseInt function, and multiplies by 0.6 and populates the data into the other element.

The solution uses jQuery as your original question was using it as well.

Try this:

 var priceFark = parseFloat($("#totalPricefark").text()); $('#totalPricefark2').html(priceFark * 0.6); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <strong id="totalPricefark">2</strong> <br/> <strong id="totalPricefark2">1</strong> 

Answer 2

you could just do something like this

const data = {
  totalPrice: 10
};

$('#totalPricefark').text(data.totalPrice * 0.6);

Answer 3

try this

  var data={}; data.totalPrice=15; var result=(parseFloat( data.totalPrice) * 0.6); $('#totalPricefark').html(result); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> <strong id="totalPricefark">0</strong> 

Answer 4

用javascript不能解决问题:(用php创建了一个新的Json对象变量。用这种方法解决了。感谢我的朋友们的帮助。
