[英]Set up JavaScript to call function with different parameters
I have the following ExtJS controller code: 我有以下ExtJS控制器代码:
init: function() {
this.control({
'#menuitem-A': { click: this.handlerA },
'#menuitem-B': { click: this.handlerB },
});
},
and the following event handlers: 和以下事件处理程序:
commonFunc: function(param1, param2) {
// do something with param1 and param2 in here
},
handlerA: function(button, event) {
this.commonFunc('param-A1', 'param-A2');
},
handlerB: function(button, event) {
this.commonFunc('param-B1', 'param-B2');
},
Problem: the current code is redundant: handlerA
and handlerB
just call commonFunc
with different parameters 问题:当前代码是多余:
handlerA
和handlerB
只是调用commonFunc
用不同的参数
Question: I would like to remove handlerA
and handlerB
and instead call
or apply
the common function commonFunc
with the arbitrary parameters within handlerA
and handlerB
functions above, for different event handlers. 问:我想删除
handlerA
和handlerB
,而是call
或apply
的共同作用commonFunc
与内任意参数handlerA
和handlerB
功能之上,针对不同的事件处理程序。 Is it possible? 可能吗?
Example: 例:
init: function() {
this.control({
'#menuitem-A': { click: /*commonFunc with ['param-A1', 'param-A2']*/ },
'#menuitem-B': { click: /*commonFunc with ['param-B1', 'param-B2']*/ },
});
},
Many thanks! 非常感谢!
how about this: 这个怎么样:
init: function() {
this.control({
'#menuitem-A': {
click: function(button, event){
this.commonFunc('param-A1', 'param-A2');
}
},
'#menuitem-B': {
click: function(button, event){
this.commonFunc('param-B1', 'param-B2');
}
}
});
},
