[英]extjs4 get selected value from combobox
Ok, this is driving me nuts again. 好的,这让我再次疯了。 I am trying to get the selected value from a combo box so I can update a grid with the correct data based on the user selection.
我试图从组合框中获取所选值,以便我可以根据用户选择使用正确的数据更新网格。 How do I do this?
我该怎么做呢?
I am using extjs 4 in MVC model. 我在MVC模型中使用extjs 4。 Here is my code:
这是我的代码:
my init inside the viewport: 我在视口内的init:
init: function() {
this.control({
'viewport > combobox': {
select: this.onChangeStacker
}
});
},
// method with pseudocode of what I want to do
onChangeStacker: function(){
selected = getSelection;
switch selected
case == stk1
load stk1
case == stk2
load stkd
}
});
this.control({
'viewport > combobox': {
change: function(cmp) {
var value = cmp.getValue();
.
.
.
}
}
});
