我有一个测验,如果你得到100%,当你加载最后一页时,它会发出警报"你得到了100%!"。虽然,它在后台加载之前加载。这是我的代码:
var chanceoflive1 = parseInt(localStorage.getItem("chanceoflive1"));
var chanceoflive2 = parseInt(localStorage.getItem("chanceoflive2"));
var chanceoflive3 = parseInt(localStorage.getItem("chanceoflive3"));
var chanceoflive4 = parseInt(localStorage.getItem("chanceoflive4"));
var chanceoflive7 = parseInt(localStorage.getItem("chanceoflive7"));
var chanceoflivefinal = (chanceoflive1||0) + (chanceoflive2||0) + (chanceoflive3||0) + (chanceoflive4||0) + (chanceoflive7||0);
var chanceoflivepercent = chanceoflivefinal * 4;
function startup(){
if (chanceoflivefinal == 25) {
alert("You Got 100%!");
}
}

<body onload="startup">
<center>
<h2 class="text">Final Results</h2>
<p id="print" class="text"></p>
<p id="print2" class="text"></p>
<img src="qrcode.jpg" height="300" length="300">
<br>
<div class="wrapper">
<a href="index.html">
<button align=center onclick="handleClick()" id="button">
<canvas width="200" height="50" id="canvas" align=center></canvas>
<span class="text" id="submit">Retry</span>
</button>
</a>
</div>
</center>
</body>
&#13;
我该如何解决这个问题?

你总是可以在script
标签内做这样的事情:
(function(){ // on document load
alert("Ready!"); // alert "ready"
})();
哦,正如 @Barmar 所说,要调用function
,您需要将startup
更改为startup()

您只是遗漏了();
这样的onload="startup();"
。
也许你也可以使用
document.onload = startup();
甚至
window.onload = startup();
