extjs-以字母数字和不区分大小写的方式对存储进行排序 [英] extjs - Sort store alphanumerically and case insensitively

问题描述

我想按字母顺序对存储(ArrayStore和GroupingStore)进行排序，并且不区分大小写.我正在使用singleSort()方法，但是区分大小写.

I want to sort store (ArrayStore and GroupingStore) alphanumerically and case INSENSITIVELY. I am using singleSort() method but it sorts case sensitively.

例如，

data = ['c', '1', 'A', 'a', 'C']
output = ['1', 'A', 'C', 'a', 'c']
myoutput = ['1', 'a', 'A', 'c', 'C'] or [['1', 'A', 'a', 'C', 'c']    // This is what I want

关于如何实现这一目标的任何建议?

Any suggestion on how to achieve this?

推荐答案

将此内容添加到您的代码中……请注意您的作用域，因为您将使页面上的所有类型都不区分大小写.我在论坛上找到了此代码，并已在3.2.1中成功使用了它.

Add this to your code... be wary of your scopes because you will make all sorts on the page case insensitive. I found this code on the forums and have used it successfully in 3.2.1.

Ext.data.Store.prototype.sortData = function(f, direction){
direction = direction || 'ASC';
var st = this.fields.get(f).sortType;
var fn = function(r1, r2) {
    var v1 = st(r1.data[f]), v2 = st(r2.data[f]);
    // ADDED THIS FOR CASE INSENSITIVE SORT
    if (v1.toLowerCase) {
        v1 = v1.toLowerCase();
        v2 = v2.toLowerCase();
    }
    return v1 > v2 ? 1 : (v1 < v2 ? -1 : 0);
};
this.data.sort(direction, fn);
if (this.snapshot && this.snapshot != this.data) {
    this.snapshot.sort(direction, fn);
}

}
