Web服务示例
$(“#Btn”)。单击(函数(事件){
警报(“点击按钮”);
});
这就是内容
代码在DOM准备就绪之前运行。将其放入DOM事件处理程序中:
$(document).ready(function() {
//Code that interacts with the DOM (such as binding event listeners...)
$("#Btn").click(function (event) {
alert("Button Clicked");
});
});

将脚本放在主体之后,以便浏览器在找到按钮后附加事件
或者将它放在document.ready中。将脚本放在正文之后,这样一旦找到按钮,浏览器就会附加事件 或者把它放在文件里。准备好了
