Question

我无法掌握如何使用jquery .trigger（）。我只是循环复选框并找到已选中的复选框。然后我尝试将这些值映射到键值对。如果我记录paymentValue和paymentName，我会得到正确的输出，例如：现金和 true ，所以我想要像 cash：true 这样的东西我的关键价值。除非我尝试运行此代码，否则我会收到 paymentName未定义错误

var filterPayment = $('input[name="filter-payment"]:checked');
var paymentObj = {};         

$(document).bind("updateFilters", function() {
    filterPayment.each( function () {
       var paymentValue = paymentObj[this.value];
       paymentValue = this.checked;   

       var paymentName = userObj[this.name];
       paymentName = this.value;             
    });
});

$(document).trigger('updateFilters', {
    paymentValue : paymentName
});

有什么想法吗？

尝试

var filterPayment = $('input[name="filter-payment"]');
var paymentObj = {};
var userObj = {};

//listern to the change event
filterPayment.change(function () {
    var paymentValue = paymentObj[this.value];
    paymentValue = this.checked;

    var paymentName = userObj[this.name];
    paymentName = this.value;

    //create a parameter object, since the key is dynamic need to use bracket notation to assign the value
    var param = {};
    param[paymentValue] = paymentName;

    $(document).trigger('updateFilters', param);
}).filter(':checked').change()

$(document).bind("updateFilters", function () {
    alert('filter updated')
});

jQuery使用.trigger（）和键值
