我正在编码randon报价机器,并且在点击“新报价”按钮时出现问题。为了简洁起见,quotes
,colors
和animations
变量的数据已被简化并缩小。所以问题是这样的。随着我不断点击按钮和一组较小的数据,我注意到响应时间变长了,颜色,引号和/或动画不会改变。这是显而易见的,动画并不总是运行。有了这一小套数据,我明白新输出可能与之前的输出完全一样,但动画仍然可以运行,有时却不会。如果没有loadQuotes()
函数并且没有window.onload = loadQuotes();
,并且我按下键盘上的F5重新加载页面,则此代码正确运行。当我将代码放在loadQuotes()
函数中并在页面底部使用window.onload = loadQuotes();
来获得初始输出时,问题就开始了。我尝试将loadQuotes()
函数之外的所有变量和randomNum()
函数(因为我假设它们是全局函数),而当我在初始页面加载后执行该操作时,单击该按钮根本不会执行任何操作。所以我关心的是如何通过按F5来按照上面所述加载页面,但是通过单击按钮。按钮没有正确更新输出
function loadQuotes() {
function randomNum(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
var quotes = [
["This is quote number one.", "Person 1"],
["This is quote number two.", "Person 2"],
["This is quote number three.", "Person 3"],
["This is quote number four.", "Person 4"],
["This is quote number five.", "Person 5"]
]
var colors = [
["#096986", "#F69679"],
["#000866", "#FFF799"],
["#7D3563", "#82CA9C"]
]
var animations = ["animated bounce", "animated flash", "animated pulse"]
var getQuotes = randomNum(0, quotes.length - 1);
var getColors = randomNum(0, colors.length - 1);
var newColor0 = colors[getColors][0];
var newColor1 = colors[getColors][1];
var newAnimation1 = animations[randomNum(0, animations.length - 1)]
var newAnimation2 = animations[randomNum(0, animations.length - 1)]
document.getElementById("quote").innerHTML = "<h1>" + quotes[getQuotes][0] + "</h1>";
document.getElementById("author").innerHTML = "<h3>" + "--- " + quotes[getQuotes][1] + "</h3>";
$(document).ready(function() {
$(".side-panel").css("background-color", newColor0);
$(".middle").css("background-color", newColor1);
$("#quote").addClass(newAnimation1);
$("#author").addClass(newAnimation2);

loadQuotes();

我已编辑并移动到一切的片断,但重新运行并点击按钮正在改变引号。你可以解释一下确切的问题。 – Iceman
我试图垃圾邮件的按钮,它几乎崩溃我的浏览器。 – technico
