How to call multiple functions on ng-change in angularJS?
提问by Suhas V
ng-change = "ControllerName.functionName()"
ng-change = "ControllerName.functionName()"
here I want to add one more function to that. How can I do that ?

Thanks in advance.

This should do the trick:
这应该可以解决问题:
ng-change = "ControllerName.functionName(); ControllerName.anotherFunction();"
回答by frikkievb
Why not rather group the functions in the controller inside another function?
为什么不将控制器中的功能分组到另一个功能中?
function onChangeGroup(){
doStuff();
doMoreStuff();
}
<input ng-change="ControllerName.onChangeGroup()"/>
Regards
问候

This is working properly but one controller in both function.
这工作正常,但两个功能中的一个控制器。
ng-change = "function1();function2();"

for angular version 1.* :
ng-change = "function1();function2();"
对于角度版本 1.* :
ng-change = "function1();function2();"
for angular version 2.* or more:
(change)= "function1();function2();"
对于 Angular 版本 2.* 或更高版本:
(change)= "function1();function2();"

You just need to add another function in the same double quotes.
您只需要在相同的双引号中添加另一个函数。
ng-change = "ControllerName.functionFirst(); ControllerName.functionSecond();"
You can use ng-change
for multi expression by adding semicolon ;
after each expression
您可以ng-change
通过;
在每个表达式后添加分号来用于多表达式
