Extjs7 store使用remoteFilter時自定義過濾條件編碼格式

7.4.0

框架默認的遠程過濾參數編碼函數在proxy類中定義，因此需要自定義Proxy，覆蓋encodeFilters方法

Ext.define('My.data.proxy.Ajax', {
    extend: 'Ext.data.proxy.Ajax',
    alias: 'proxy.my-ajax',
    filterParam:'filter_options',
    encodeFilters: function (filters) {
		// 根據filters構造過濾參數
		return ;
    }
});

...
getParams: function(operation) {
    ...
    if (filterParam && filters && filters.length > 0) {
        params[filterParam] = me.encodeFilters(filters);
    }

    return params;
},
...
encodeFilters: function(filters) {
    var out = [],
        length = filters.length,
        encode, i;

    for (i = 0; i < length; i++) {
        encode |= filters[i].serializeTo(out);
    }

    // If any Filters return Objects encapsulating their full state, then the parameters
    // needs JSON encoding.
    return encode ? this.applyEncoding(out) : out;
},
...
applyEncoding: function(value) {
    return Ext.encode(value);
},
