问题描述
嗨
我有4个ASP文本框,其中3个是我们可以输入整数值的值,第4个文本框是只读的.
例如,在第一个文本框中,他们输入的值为20.
然后第二个文本框在这种情况下最多允许20个,其余两个文本框我需要预填充0(零).
在第二种情况下,可以输入的第二个文本框的值是15,第三个文本框的值是3,然后
第四个文本框应预填其余的"2".
最后,三个(2nd,3rd,4th)文本框值的总和应与第一个texbox值相匹配...........
请帮助我任何一个..

For example In 1st Textbox they entered the value is 20.

In second case the can enter 2 nd textbox vlaue is 15 3rd textbox value is 3 then
4 th textbox should prepoulate remaing ''2''.
finally the sum of three(2nd,3rd,4th)textboxes values should match with 1st texbox value ...........

推荐答案
您可以使用以下javascript函数:
You can use following javascript function:
function Matchvalues()
{
var value1 = document.getElementById('TextBox1').value;
var value2 = parseInt(document.getElementById('TextBox2').value) +
parseInt(document.getElementById('TextBox3').value) +
parseInt(document.getElementById('TextBox4').value);
if (value1 != value2) {
alert('value in 1st TextBox and sum of Textbox2,Textbox3,Textbox4 are not matched');
return false;
}
else {
alert('value in 1st TextBox and sum of Textbox2,Textbox3,Textbox4 are matched');
return true;
}
}
在按钮的OnClientClick事件上调用此函数.

call this function on OnClientClick event of a button.
