javascript - 发送一个 ajax POSt 选中的复选框以及选定的下拉列表

Question

选中我们决定使用此代码保留的复选框

$('.list input[type=checkbox]').on('change', function () {
    var favorite = {};

    $('.list input[type=checkbox]:checked').each(function () {
        var $el = $(this);
        var name = $el.attr('name');
        if (typeof (favorite[name]) === 'undefined') {
            favorite[name] = [];
        }
        favorite[name].push($el.val());
    });

    $.ajax({
        url: '/Search.asp',
        type: 'POST',
        data: $.param(favorite),
        dataType: 'text',
        success: function (data) {
            $("#ExSearchForm").html(data)
                .find('input[type=checkbox]').each(function () {
                    var $el = $(this);
                    var name = $el.attr('name');
                    var value = $el.attr('value')
                    if (favorite[name] && favorite[name].indexOf(value) !== -1) {
                        $el.prop('checked', true);
                    }
                });
        }
    });
});

现在我们还需要保存类似的下拉值

$('.list Select[option]').on('change', function () {
    var favorite = {};

    $('.list Select[option]:selected').each(function () {
        var $el = $(this);
        var name = $el.attr('name');
        if (typeof (favorite[name]) === 'undefined') {
            favorite[name] = [];
        }
        favorite[name].push($el.val());
    });

    $.ajax({
        url: '/Search.asp',
        type: 'POST',
        data: $.param(favorite),
        dataType: 'text',
        success: function (data) {
            $("#ExSearchForm").html(data)
                .find('Select[option]').each(function () {
                    var $el = $(this);
                    var name = $el.attr('name');
                    var value = $el.attr('value')
                    if (favorite[name] && favorite[name].indexOf(value) !== -1) {
                        $el.prop('selected', true);
                    }
                });
        }
    });
});

可以将其合并到一个ajax帖子中吗？

可以通过使用通用函数onValueChange并将其附加为复选框和下拉菜单的更改事件的监听器来实现:

function onValueChange() {
    var favorite = {};

    $('.list input[type=checkbox]:checked').each(function () {
        var $el = $(this);
        var name = $el.attr('name');
        if (typeof (favorite[name]) === 'undefined') {
            favorite[name] = [];
        }
        favorite[name].push($el.val());
    });
 $('.list Select[option]:selected').each(function () {
        var $el = $(this);
        var name = $el.attr('name');
        if (typeof (favorite[name]) === 'undefined') {
            favorite[name] = [];
        }
        favorite[name].push($el.val());
    });

    $.ajax({
        url: '/Search.asp',
        type: 'POST',
        data: $.param(favorite),
        dataType: 'text',
        success: function (data) {
            $("#ExSearchForm").html(data)
                .find('input[type=checkbox]').each(function () {
                    var $el = $(this);
                    var name = $el.attr('name');
                    var value = $el.attr('value')
                    if (favorite[name] && favorite[name].indexOf(value) !== -1) {
                        $el.prop('checked', true);
                    }
                });
            $("#ExSearchForm").html(data)
                .find('Select[option]').each(function () {
                    var $el = $(this);
                    var name = $el.attr('name');
                    var value = $el.attr('value')
                    if (favorite[name] && favorite[name].indexOf(value) !== -1) {
                        $el.prop('selected', true);
                    }
                });
        }
    });
};
$('.list input[type=checkbox]').on('change',onValueChange);     
$('.list Select[option]').on('change', onValueChange);
