項目中需要實現一個點擊按鈕復制鏈接的功能,網上看到的幾款插件,ZeroClipboard是通過flash實現的復制功能,隨著越來越多的提議廢除flash,能不能通過JS來實現復制剪切呢,今天分享一個兼容IE7浏覽器復制的插件給大家,支持使用javascript實現復制、剪切和粘貼。
方法。
復制
var copy = new clipBoard(document.getElementById('data'), { beforeCopy: function() { }, copy: function() { return document.getElementById('data').value; }, afterCopy: function() { } });
復制將自動被調用,如果你想要自己調用:
var copy = new clipBoard(document.getElementById('data')); copy.copyd();
document.getElementById('data') :要獲取的對象, 你也可以使用jQuery $('#data')
剪切
基本上與復制的實現方法相同:
var cut = new clipBoard(document.getElementById('data'), { beforeCut: function() { }, cut: function() { return document.getElementById('data').value; }, afterCut: function() { } });
或者
var cut = new clipBoard(document.getElementById('data')); cut.cut(); paste var paste = new clipBoard(document.getElementById('data'), { beforePaste: function() { }, paste: function() { return document.getElementById('data').value; }, afterPaste: function() { } });
或者
var paste = new clipBoard(document.getElementById('data')); paste.paste();
完整代碼:
(function(name, fun) { if (typeof module !== 'undefined' && module.exports) { module.exports = fun(); } else if (typeof define === 'function' && define.amd) { define(fun); } else { this[name] = fun(); } })('clipBoard', function() { "use strict"; function clipBoard(tar, options) { this.options = options || {}; this.tar = tar[0] || tar; // if options contain copy, copy will be applied soon if (this.options.copy) { this.copyd(); } if(this.options.cut) { this.cut(); } if(this.options.paste) { this.paste(); } } clipBoard.prototype.copyd = function(value) { // before the copy it will be called, you can check the value or modify the value if (this.options.beforeCopy) { this.options.beforeCopy(); } // if the options set copy function, the value will be set. then get the paramer value. // above all, if the value is null, then will be set the tar of value value = value || this.tar.value || this.tar.innerText; if (this.options.copy) { value = this.options.copy(); } // for modern browser if (document.execCommand) { var element = document.createElement('SPAN'); element.textContent = value; document.body.appendChild(element); if (document.selection) { var range = document.body.createTextRange(); range.moveToElementText(element); range.select(); } else if (window.getSelection) { var range = document.createRange(); range.selectNode(element); window.getSelection().removeAllRanges(); window.getSelection().addRange(range); } document.execCommand('copy'); element.remove ? element.remove() : element.removeNode(true); } // for ie if (window.clipboardData) { window.clipboardData.setData('text', value); } // after copy if (this.options.afterCopy) { this.options.afterCopy(); } };
