为什么在asp.net中调用javascript函数时需要分号 [英] Why is the semicolon required while calling a javascript function in asp.net

问题描述

当我没有尝试;服务器显示错误。

为什么最有必要让函数不用分号调用



考虑我有javascript代码为

函数myfunction（）{

//代码部分

}







< asp：RadioButtonList ID =rblistGenderrunat =serveronclick =myfunction（）;>





为什么需要onclick方法的分号？



我必须在用户时执行我的代码更改单选按钮列表的值。

When I tried without ; the server shows error.
Why is it most necessary so that function doesn't call without semicolon

Consider I am having javascript code as
function myfunction(){
// code part
}



<asp:RadioButtonList ID="rblistGender" runat="server" onclick="myfunction();">


Why the semicolon at the onclick method is needed?

I have to execute my code whenever the user changes the value of the radio button list.

推荐答案

为什么用句号结束​​句子并以大写字母开头？所以我们知道你的句子何时开始和结束。同样的原因，js喜欢看到一个分号，它告诉它这是最后的陈述。我认为很多js实现都不需要;但是对于启动代码段的事情来说最重要的是。

Why do you end sentences with a period and start them with a capital letter? So we know when your sentences begin and end. Same reason that js likes to see a semi-colon, it tells it this is the final statement. I think a lot of js implementations don't require the ; but it is most important when it comes to things that start code segments.

if (x == 1)
   x = x + 1;

如果x为1，则上述意味着增加x

The above means increment x if x is 1.

if (x == 1);
   x = x + 1;

上述意味着如果x为1则什么都不做。然后总是增加x。



作为最佳实践，你应该总是使用它们。

The above means that if x is 1 do nothing. Then always increment x.

As best practice you should always use them.
