为什么我的 JavaScript 代码不工作？
我不断收到此代码的“语法错误：意外标识符”JS 错误：
function hashStuff() {
var messageID = window.location.hash.replace('#inbox-', '');
var msgSubject = $('#subject_' + messageID).html();
setTimeout("readMessage2(" + messageID + ", " + msgSubject + ");", 300);
}
if (window.location.hash) {
setTimeout("hashStuff();", 400);
}
我也尝试过：
if (window.location.hash) {
function hashStuff() {
var messageID = window.location.hash.replace('#inbox-', '');
var msgSubject = $('#subject_' + messageID).html();
setTimeout("readMessage2(" + messageID + ", " + msgSubject + ");", 300);
}
setTimeout("hashStuff();", 400);
}
它们都不起作用。
我试图做的是从元素中获取信息，但我猜页面尚未加载，所以我需要它在一秒钟后触发。我把它放在一个函数中，这样我就可以使用超时，但它不起作用。
有什么想法吗？提前致谢。
I keep getting the "Syntax Error: Unexpected identifier" JS error with this code:
function hashStuff() {
var messageID = window.location.hash.replace('#inbox-', '');
var msgSubject = $('#subject_' + messageID).html();
setTimeout("readMessage2(" + messageID + ", " + msgSubject + ");", 300);
}
if (window.location.hash) {
setTimeout("hashStuff();", 400);
}
I've also tried:
if (window.location.hash) {
function hashStuff() {
var messageID = window.location.hash.replace('#inbox-', '');
var msgSubject = $('#subject_' + messageID).html();
setTimeout("readMessage2(" + messageID + ", " + msgSubject + ");", 300);
}
setTimeout("hashStuff();", 400);
}
Neither of them work.
What I was trying to do was get information from the elements but I guess the page wasn't loaded yet so I need it to trigger after a second. I put it in a function so I can use a timeout and it will not work.
Any ideas? Thanks in advance.

如果您的 messageID 类似于 1234 并且 msgSubject 是 Hello World，那么正在评估的语句是：
显然，这是不正确的并且会引发错误。
正确的代码是：
If your messageID is something like 1234 and the msgSubject is Hello World, then the statement being evaluated is:
Which, clearly, is incorrect and error-inducing.
The correct code is:
您可以在
$(document).ready(function() {//script here});中运行脚本。这将确保它在所有元素加载后运行。You can run the script inside
$(document).ready(function() {//script here});. That will make sure that it is run after all the elements have loaded.尝试将代码包装在
ready块中：try wrapping your code inside
readyblock:
