我在Google上进行了研究,并尝试了一些方法,但实际上没有用。
var name,child,result;
function setvalues()
{
name=Number(document.getElementById("name").value);
child=Number(document.getElementById("child").value);
}
on that name field user has to enter some number to calculate,, its was calculating but just a number not with an currency sign... I seen some of the JavaScript function to change the currency format but its not very clear... and how to add three vaules together and show in one textbox with £ sign 在该名称字段上,用户必须输入一些要计算的数字,它正在计算但只是一个不带货币符号的数字...我看到了一些JavaScript函数来更改货币格式,但它不是很清楚...并且如何将三个值加在一起并在带有£符号的文本框中显示

我建议如果您使用的是货币(这在JavaScript中可能尤其痛苦)。 I would recommend using a library to handle this for you.
我建议使用一个库来为您处理。 I have used accounting.js in the past and it works very well for these sorts of things:
我过去使用过accounting.js,它可以很好地用于以下方面:
