Js assigns values to onclick and transmits Parameters

1) when the method does not have a parameter, you can use the onclick method name window to assign a value. onloadfunction () {$ (& amp; #39; btnTest & amp; #39 ;). onclicktest;} functiontest () {alert (val) ;}2) when the method has parameters, use onclick...

1) when the method does not have a parameter, you can directly use onclick = method name to assign a value.

Window. onload = function (){
$ ('Btntest'). onclick = test;
}
Function test (){
Alert (val );
}

2) When the method has parameters, an error occurs when onclick = method name (parameter) is used. You need to add function () before the method name ()

Window. onload = function (){
$ ('Btntest'). onclick = function () {test (1 )};
}
Function test (val ){
Alert (val );
}
