一个比较变态的js传值，Query的bindajax闭包上下文传值

Posted 2020-09-21

var getIDNameList = function (list, selected, text, btn, actionUrl, defaultKey, deleteKey, keyName, valueName, callBackFuc) 
{
    btn.bind("click keyup", { sText: text }, function (e) {
        $.ajax({
            url: actionUrl,
            contentType: "application/json",
            type: "GET",
            success: $.proxy(function (data) {
                var comparStr = this.val();
                for (var i = 0; i < data.length; i++) {
                    
                    if (data[i][valueNameStr].indexOf(comparStr) == -1)
                        continue;
                }
            }, e.data.sText)
        });
    });
}

//调用
var i=1;
getIDNameList(
             $(‘#List‘ + i),
             $(‘#S‘ + i),
             $(‘#searchText‘ + i),
