问题描述
当我按下添加按钮时,我只想在两个文本框中添加两个数字并得到总和。
但是有一个错误,我无法弄清楚。感谢您是否可以帮助我。
以下是代码:
I just want to add two numbers to the two text boxes and get the sum, when I press the Add button.
But there is an error and I can''t figure it out. Appreciate if you can help me.
Here is the code:
<html>
<head>
<script type="text/javascript">
function AddTwo(x,y)
{
var x;
var y;
var sum;
sum=num1+num2;
document.write("Summation is "+sum);
}
</script>
</head>
<body>
<label>Number 1</label>
<input type="text" name="num1" value="" />
<label>Number 2</label>
<input type="text" name="num2" value="" />
<br />
<input type="button" onclick="AddTwo(parseInt(num1.value),parseInt(num2.value))" value="Add Numbers" />
</body>
</html>
推荐答案
<script type="text/javascript">
function AddTwo(num1,num2)
{
var sum;
sum=num1+num2;
document.write("Summation is "+sum);
}
</script></script>
onclick="AddTwo(parseInt(num1.value),parseInt(num2.value))"
所以,我在两个文本框中都添加了id属性。
So, I added id attribute to both the textboxes.
<html>
<head>
<script type="text/javascript">
function AddTwo(x,y)
{
var x;
var y;
var sum;
sum = x + y; - This line is changed
document.write("Summation is " + sum);
return false;
}
</script>
</head>
<body>
<label>Number 1</label>
<input type="text" name="num1" value="" id="num1"/>
<label>Number 2</label>
<input type="text" name="num2" value="" id="num2"/>
<br />
<input type="button" onclick="AddTwo(parseInt(num1.value),parseInt(num2.value))" value="Add Numbers" />
</body>
</html>
现在这段代码工作正常。
谢谢......
Now this code is working fine.
