Question

我试图找到如何让jQuery脚本在启动单击事件时正常工作，脚本计算容器的高度（此脚本在加载时出现在页面的开头，并且100％工作）但我现在正试图让它在.click事件中工作。

如果有人知道我应该如何实现这一点，我将非常感激。

P.S。我已经尝试过准备文件;等待DOM加载，但没有雪茄。

$(document).ready(function() {
    $("#hidden4").click(function(event) {
        event.preventDefault();
        $("#hidden4-1").slideToggle();

        var classDown = $('#hidden4 div.down').attr('class');
        var classUp = $('#hidden4 div.up').attr('class');

        if(classDown == 'down') {
            $("#hidden4 div.down").attr("class","up");
        }
        else if(classUp == 'up') {
            $("#hidden4 div.up").attr("class","down"); 
        }
            // Attain the absolute height of the container id container and assign to a usable variable
            var height = $("#container").height();
            alert (height);
            // Use the previous variable, divide by 4 then round that up and multiply by 4 and assign to new variable
            var newHeight = Math.ceil(height / 4) * 4;

            // Create a new variable and add the string "center" to it
            var finalHeight = "center ";

            // Using the previous variable add to it using the first 2 variables subtracting to find the difference and add 2
            finalHeight += (newHeight - height)+2;

            // Using the previous variable add to it the string "px" for the css selector usage
            finalHeight += "px";

            // Update the CSS of the required element altering the background position with the final variable
            $(".contentFooter").css('background-position', finalHeight);
    });
});

提前谢谢。

您正在ready（）内嵌入ready（）。不要做这样的事情。试试这个：

$(document).ready(function () {
    $("#hidden4").click(function (event) {
        event.preventDefault();
        $("#hidden4-1").slideToggle();

        var classDown = $('#hidden4 div.down').attr('class');
        var classUp = $('#hidden4 div.up').attr('class');

        if (classDown == 'down') {
            $("#hidden4 div.down").attr("class", "up");
        }
        else if (classUp == 'up') {
            $("#hidden4 div.up").attr("class", "down");
        }
        // Attain the absolute height of the container id container and assign to a usable variable
        var height = $("#container").height();
        alert(height);
        // Use the previous variable, divide by 4 then round that up and multiply by 4 and assign to new variable
        var newHeight = Math.ceil(height / 4) * 4;

        // Create a new variable and add the string "center" to it
        var finalHeight = "center ";

        // Using the previous variable add to it using the first 2 variables subtracting to find the difference and add 2
        finalHeight += (newHeight - height) + 2;

        // Using the previous variable add to it the string "px" for the css selector usage
        finalHeight += "px";

        // Update the CSS of the required element altering the background position with the final variable
        $(".contentFooter").css('background-position', finalHeight);
    });
});

btw，如果你想在页面加载和点击时同时执行容器高度计算脚本，那么将代码放在一个函数中并在ready（）和click（）中运行该函数。

更新：

$("#foo").slideToggle(function() {
    // this code executes AFTER slideToggle has completed
});

我认为你不需要在jquery点击中嵌套另一个$（document）.ready（），因为在你应用click事件时DOM已经准备就绪。

在DOM加载.click事件后，jQuery脚本工作？
