Two Methods for passing parameters to onclick by js _ javascript skills

This article mainly introduces two methods for assigning parameters to onclick by js. If you need them, refer to 1) when there is no parameter in the method, you can directly use onclick = method name to assign values.

The Code is as follows:

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 ()

The Code is as follows:

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