Question

I would like to override one method

onMouseUp:function(evt){
if(evt.target===this.domNode||!this._highlighted_option){
return;
}else{
if(evt.target==this.previousButton){
this.onPage(-1);
}else{
if(evt.target==this.nextButton){
this.onPage(1);
}else{
var tgt=evt.target;
while(!tgt.item){
tgt=tgt.parentNode;
}

in my JavaScript file.

How can I do that?

Answer 1

Literally, overwrite it using the same object and same method name.

var object = {
    'method': function() {
        // original script
    }
};

// your script

object.method = function() {
    // your script, original gets overwritten
};

After a quick google and clicking the first result, I found a very simular thread which is probably more accurate for your… “problem”: Dojo: how to use own onMove event (overwrite)
