使用angularjs观察下拉列表的选定值以填充数组取决于所选值 [英] watch the selected value of dropdown with angularjs to populate an array depends on the selected value

问题描述

我有这个小提琴 http://jsfiddle.net/sheko_elanteko/Anj3w/9/ [ ^ ]



我想检查模型sectionSelect的选定值，并根据所选的值，将它设置为1或2，我想用新的值填充newArr，按顺序排列相应地过滤最低和最高价格。



我现在正在做的是......

I have this fiddle http://jsfiddle.net/sheko_elanteko/Anj3w/9/[^]

I want to check for the selected value of the model "sectionSelect", and based on the selected value, weather it's "1" or "2", I want to fill the newArr with the new values that match the selected, in order to filter the min and max prices accordingly.

What I'm doing right now is this ...

if ($scope.sectionSelect == 1) {

    for($i=0; $i < arr.length; $i++){

        if(arr[$i]['section'] === 1) {
            newArr.push(arr[$i]['value']);
        }
    }

} else if($scope.sectionSelect == 2) {
    for($i=0; $i < arr.length; $i++){

        if(arr[$i]['section'] === 2) {
            newArr.push(arr[$i]['value']);
        }
    }
}

但这似乎不起作用。

我该怎么办？

But that doesn't seem to work.
What should I do?
