Get DOM element is javascript
document.getElementById()
document.getElementsByName()
document.getElementsByTagName()
document.getElementsByClassName()
// Parameter same to parameter css selector
document.querySelector()
document.querySelectorAll()
// Specific for getting html element
document.documentElement()
// Specific for getting body element
document.body()
Generate clicking event in js
<html>
<head>
<title>usually function</title>
</head>
<script>
function load(){
//下面两种方法效果是一样的
document.getElementById("target").onclick();
document.getElementById("target").click();
}
function test(){
alert("test");
}
</script>
<body onload="load()">
<button id="target" onclick="test()">test</button>
</body>
<html>
Remark.
btnObj.click() is to actually click the button with the program, triggering the button's onclick() event
btnObj.onclick() simply calls the method pointed to by btnObj's onclick, which is just a method call and does not trigger the event.
