我在我的页面上有一个使用 Jquery 的 javascript 函数。我想让它在页面加载时自动启动此功能，但用户仍然可以与该功能进行交互。这是一个涉及选择将隐藏和淡入新 div 的链接的功能。我也试图让这种情况自动发生。

$(document).ready(function() {


        $('#tablecell1').click((function () {
    var last_image = null;

    return function () {
        if (last_image) {
            $('#tablecell1 .selected').attr('src', last_image).removeClass('selected');
        }

        var $clicked_image = $('img', this);
        last_image = $clicked_image.attr('src');
        $clicked_image.attr('src', 'NewsBarAZ/Article-Nav-Bar2_01.gif').addClass('selected');
        $('#img2').attr('src','NewsBarAZ/Article-Nav-Bar1_02.gif');
        $('#img3').attr('src','NewsBarAZ/Article-Nav-Bar1_03.gif');
        $('#img4').attr('src','NewsBarAZ/Article-Nav-Bar1_04.gif');
        $('#img5').attr('src','NewsBarAZ/Article-Nav-Bar1_05.gif');

    }
})());

    $('#tablecell2').click((function () {
    var last_image = null;

    return function () {
        if (last_image) {
            $('#tablecell2 .selected').attr('src', last_image).removeClass('selected');
        }

        var $clicked_image = $('img', this);
        last_image = $clicked_image.attr('src');
        $clicked_image.attr('src', 'NewsBarAZ/Article-Nav-Bar2_02.gif').addClass('selected');

您可以使用.trigger()触发代码中的任何事件

作为

  $('#link_1').trigger('click');

给函数起一个名字，然后在适当的地方用参数调用它。

function hideLinkFadeDiv(link, div) {
  link.hide();
  div.fadeIn();
};

$(function() { //Personal Preference Instead of $(document).ready(function() {

  hideLinkFadeDiv($('#foo'), $('#bar'));
  //Runs when the document loads

  $('#foo').on('click', function() { 
    hideLinkFadeDiv($(this), $('#bar'));
    //runs when #foo is clicked
  });
});

我保留了您提供的函数的内部工作原理，但您应该考虑使用类而不是 id。

// Once the DOM is ready
$(function(){
    tableClick("1", {"2", "3", "4", "5"});
    tableClick("2", {"1", "3", "4", "5"});
    tableClick("3", {"1", "2", "4", "5"});
    tableClick("4", {"1", "2", "3", "5"});
    tableClick("5", {"1", "2", "3", "4"});

    $('.preview').hide();

    linkClick("1", {"1", "2", "3", "4"});
    linkClick("2", {"0", "2", "3", "4"});
    linkClick("3", {"0", "1", "3", "4"});
    linkClick("4", {"0", "1", "2", "4"});
    linkClick("5", {"0", "1", "2", "3"});
});

// tableClick
var tableClick = function(el, order){
    $("#tablecell" + el).click(function(){
        var last_image = null;

        return function () {
            if (last_image) {
                $(this).find(".selected").attr("src", last_image).removeClass("selected");
            }

            var $clicked_image = $("img", this);
            last_image = $clicked_image.attr("src");
            $clicked_image.attr("src", "NewsBarAZ/Article-Nav-Bar2_0" + el +".gif").addClass("selected");
            for (var i = 1; i <= order.length; i++ ){
                $("#img" + order[i]).attr("src","NewsBarAZ/Article-Nav-Bar1_0" + order[i] + ".gif");
            }
        }
    });
};

// linkClick
var linkClick = function(el, hideElements){
    $("#link_" + el).click(function(){
        // hide elements
        for (var i = 0; i < hideElements.length; i++){      
            if (hideElements[i] == "0") $("#latest_story_main").hide();
            else $("#latest_story_preview" + hideElements[i]).hide();
        }

        // show active
        var active = parseInt(el) - 1;

        if (active == 0) active = "main";
        else active = "preview" + active;

        $("#latest_story_" + active).fadeIn(800);
    });
};
