Pemikiran menjelaskan apa perbedaan antara offsetHeight, clientHeightdan scrollHeightatau offsetWidth, clientWidthdan scrollWidth?
Seseorang harus mengetahui perbedaan ini sebelum bekerja di sisi klien. Kalau tidak setengah dari hidup mereka akan dihabiskan untuk memperbaiki UI.
Biola , atau sebaris di bawah:
function whatis(propType) {
var mainDiv = document.getElementById("MainDIV");
if (window.sampleDiv == null) {
var div = document.createElement("div");
window.sampleDiv = div;
}
div = window.sampleDiv;
var propTypeWidth = propType.toLowerCase() + "Width";
var propTypeHeight = propType + "Height";
var computedStyle = window.getComputedStyle(mainDiv, null);
var borderLeftWidth = computedStyle.getPropertyValue("border-left-width");
var borderTopWidth = computedStyle.getPropertyValue("border-top-width");
div.style.position = "absolute";
div.style.left = mainDiv.offsetLeft + Math.round(parseFloat((propType == "client") ? borderLeftWidth : 0)) + "px";
div.style.top = mainDiv.offsetTop + Math.round(parseFloat((propType == "client") ? borderTopWidth : 0)) + "px";
div.style.height = mainDiv[propTypeHeight] + "px";
div.style.lineHeight = mainDiv[propTypeHeight] + "px";
div.style.width = mainDiv[propTypeWidth] + "px";
div.style.textAlign = "center";
div.innerHTML = propTypeWidth + " X " + propTypeHeight + "( " +
mainDiv[propTypeWidth] + " x " + mainDiv[propTypeHeight] + " )";
div.style.background = "rgba(0,0,255,0.5)";
document.body.appendChild(div);
}
document.getElementById("offset").onclick = function() {
whatis('offset');
}
document.getElementById("client").onclick = function() {
whatis('client');
}
document.getElementById("scroll").onclick = function() {
whatis('scroll');
}
#MainDIV {
border: 5px solid red;
}
<button id="offset">offsetHeight & offsetWidth</button>
<button id="client">clientHeight & clientWidth</button>
<button id="scroll">scrollHeight & scrollWidth</button>
<div id="MainDIV" style="margin:auto; height:200px; width:400px; overflow:auto;">
<div style="height:400px; width:500px; overflow:hidden;">
</div>
</div>
