A couple potential issues: first, your DOM element id
is "title", not "Title".几个潜在问题:首先,您的 DOM 元素
id
是“标题”,而不是“标题”。 So your function should be:所以你的功能应该是:
function funct1() {
document.getElementById("title").innerHTML = "Bye";
}
The next potential issue is that the jQuery load
method is asynchronous, so you'll want to make sure you execute funct1
function in the load
callback to make sure the DOM element has been loaded fist:下一个潜在问题是 jQuery
load
方法是异步的,因此您需要确保在load
回调中执行funct1
函数以确保 DOM 元素已被加载:
$('#PartDiv').load('/Part.html', funct1);
