过滤器中逻辑判断条件else if (999999 >= +data > 9999) {} 这种写法不起作用
```
// 数据优化过滤器
template.defaults.imports.dataOptimize = function (data) {
    var resultData = ''
    if (+data > 999999) {
        resultData = (+data / 10000).toFixed(0) + '万'
    } else if (999999 >= +data > 9999) { 
        resultData = (+data / 10000).toFixed(2) + '万'
    } else {
        resultData = +data
    }
    return resultData
}
```

```
else if (999999 >= +data > 9999) { 
        resultData = (+data / 10000).toFixed(2) + '万'
 } 
这个判断条件不生效
```
```
换成这种写法生效
else if (999999 >= +data  && +data > 9999) {
        resultData = (+data / 10000).toFixed(2) + '万'
}
```
