在js中实现copy。看似很简单的功能。实际上却有点复杂。因为只有能select的元素或者contentEditable的元素才支持document.execCommand(‘copy‘)，所以经过百度之后发现了
range这么个属性
function copy(copyEle) { ???????if (copyEle.nodeName.toLowerCase() === "input") { ???????????copyEle.select(); ???????????document.execCommand(‘copy‘); ???????} else { ???????????var range = document.createRange(); ???????????var selection = window.getSelection(); ???????????range.selectNode(document.getElementById(‘href‘)); ???????????if (selection.rangeCount > 0) selection.removeAllRanges(); ???????????selection.addRange(range); ???????????document.execCommand(‘copy‘); ???????????selection.removeAllRanges(); ???????} ???} ???document.querySelector("#copy").addEventListener("click", function() { ???????var copyElement = document.querySelector("#href"); ???????copy(copyElement); ???}, false);目前不支持安卓
