这个多onChange事件是否有效

Question

I have multiple functions that need to fire on the onChange event will this work?

I cannot combine the functions.

 onChange="avgFloatPipe(), ReserveFloatingPipe()" 

Thanks!

Answer 1

onChange="avgFloatPipe(); ReserveFloatingPipe();" if you insist on doing it inline and not making a third function that calls the other two.

Answer 2

If you plan on doing things inline that syntax should be fine. You could also terminate each function call with a semicolon.

 function test1() { alert(1); } function test2() { alert(2); } 

 <input onchange="test1(), test2();" /><br /> or separating the statements<br /> <input onchange="test1(); test2();" /> 

You could also wrap the functions with a third function and call them both

 function test1() { alert(1); } function test2() { alert(2); } function test3() { test1(); test2(); } 

 <input onchange="test3()" /> 

A third option is to bind the event using javascript. One way to do this is by using an anonymous function.

 function test1() { alert(1); } function test2() { alert(2); } document.getElementById("example").onchange = (function () { test1(); test2(); }); 

 <input id="example" /> 

Answer 3

只需用半冒号分隔功能即可：

onChange="avgFloatPipe(); ReserveFloatingPipe()"
