JavaScript can implement the function of copying or cutting content to the clipboard

The project needs to implement the function of clicking the button to copy the link. Several plug-ins I have seen online. ZeroClipboard is a copy function implemented through flash. With more and more proposals to abolish flash, can copy and cut through JS? Today I share a plug-in compatible with IE7 browser copying to everyone, supporting the use of javascript to achieve copy, cut and paste.

method.

copy

 var copy = new clipBoard(document.getElementById('data'), { beforeCopy: function() { }, copy: function() { return document.getElementById('data').value; }, afterCopy: function() { }});

Copy will be called automatically if you want to call it yourself:

 var copy = new clipBoard(document.getElementById('data'));copy.copyd();

document.getElementById('data'): The object to be retrieved, you can also use jQuery $('#data')

Cut

Basically the same as the implementation method of copying:

 var cut = new clipBoard(document.getElementById('data'), { beforeCut: function() { }, cut: function() { return document.getElementById('data').value; }, afterCut: function() { }});

or

 var cut = new clipBoard(document.getElementById('data'));cut.cut();pastevar paste = new clipBoard(document.getElementById('data'), { beforePaste: function() { }, paste: function() { return document.getElementById('data').value; }, afterPaste: function() { }});

or

 var paste = new clipBoard(document.getElementById('data')); paste.paste();

Complete code:

 (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 parameter 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(); } };
