Question

我在数组中分配了一个带数组的变量，即

var encounter_names = new Array();
encounters.encountersDB.each(function(encounter) { encounter_names.push(new Array(encounter.key, encounter.name))})

这是我的for循环语句，如下所述

for (var i = 0; i < encounter_names.length; i++) {
    window['li' + i] = $("li[key='" + encounter_names[i][0] + "']")
    window['li' + i] = $("<li key='" + encounter_names[i][0] + "' class='list'><a class='arrow_'+ encounter_names[i][0] +'" + encounter_names[i][0] + "' href='#'>" + encounter_names[i][1] + "</a></li>")
    $('.arrow_' + encounter_names[i][0] + '').click(function (event) {
        encounters.show(window['key' + i]);
        event.preventDefault();
    })
    encounters_list.append(encounter_names[i][0])
}

当我点击href链接时，我在控制台日志中收到以下错误：

TypeError: Result of expression 'encounter_names[i]' [undefined] is not an object.

欢迎任何建议。

我认为遇见.encountersDB是一个对象，而不是一个html对象？问题是：每个函数都有两个参数：当前索引和元素。所以你只需将其更改为：

var encounter_names = []; // short form for new Array()
$.each(encounters.encountersDB, function(index, encounter) {
  encounter_names.push([encounter.key, encounter.name]);
})

Jquery单击里面的href链接for循环
