Add semi-colons ;
to the end of the function calls in order for them both to work.
;
在函数调用的末尾添加分号,以便它们都能工作。
<input id="btn" type="button" value="click" onclick="pay(); cls();"/>
I don't believe the last one is requiredbut hey, might as well add it in for good measure.
我不认为最后一个是必需的,但是,嘿,不妨将其添加进来以更好地衡量。
Here is a good reference from SitePoint http://reference.sitepoint.com/html/event-attributes/onclick

You can create a single function that calls both of those, and then use it in the event.
您可以创建一个调用这两个函数的函数,然后在事件中使用它。
function myFunction(){
pay();
cls();
}
And then, for the button:
然后,对于按钮:
<input id="btn" type="button" value="click" onclick="myFunction();"/>

You can call the functions from inside another function
您可以从另一个函数内部调用这些函数
<input id ="btn" type="button" value="click" onclick="todo()"/>
function todo(){
pay(); cls();
}

With jQuery :
使用 jQuery :
jQuery("#btn").on("click",function(event){
event.preventDefault();
pay();
cls();
});

Binding events from html is NOT recommended. This is recommended way:
不推荐从 html 绑定事件。这是推荐的方式:
document.getElementById('btn').addEventListener('click', function(){
pay();
cls();
});

Just to offer some variety, the comma operatorcan be used too but some might say "noooooo!", but it works:
只是为了提供一些多样性,也可以使用逗号运算符,但有些人可能会说“noooooo!”,但它有效:
<input type="button" onclick="one(), two(), three(), four()"/>

onclick="pay(); cls();"
however, if you're using a return statement in "pay" function the execution will stop and "cls" won't execute,
但是,如果您在“pay”函数中使用 return 语句,则执行将停止并且“cls”不会执行,
a workaround to this:
解决方法:
onclick="var temp = function1();function2(); return temp;"

put a semicolon between the two functions as statement terminator.
在两个函数之间放置一个分号作为语句终止符。
