问题描述

我有Web应用程序,主要用于在移动设备上运行。我有一个按钮,它将复制到设备剪贴板传递的文本。我为此使用JavaScript。我的代码在所有移动设备上运行良好,除了iphone和ipad。
任何人都知道可能是什么问题?
这里是我的代码:
$ b $ pre $ CopyToClipboard = function(text,fallback){
var $ t = $('< textarea />');
$ t.val(text).appendTo('body');
$ t.select();
document.execCommand('copy');
$ t.remove();
返回true;
};

我也尝试过这种方式,但没有结果,仍然无法在iPhone上工作

  function detectIE(){
var ua = window.navigator.userAgent;

var msie = ua.indexOf('MSIE');
if(msie> 0){
// IE 10或更旧版本=>返回版本号
返回parseInt(ua.substring(msie + 5,ua.indexOf('。',msie)),10);
}

var trident = ua.indexOf('Trident /');
if(trident> 0){
// IE 11 =>返回版本号
var rv = ua.indexOf('rv:');
return parseInt(ua.substring(rv + 3,ua.indexOf('。',rv)),10);
}

var edge = ua.indexOf('Edge /');
if(edge> 0){
// IE 12 =>返回版本号
返回parseInt(ua.substring(edge + 5,ua.indexOf('。',edge)),10);
}

//其他浏览器
return false;

function copytext(text){
if(detectIE()){
window.clipboardData.setData('Text',text);
}
var textField = document.createElement('textarea');
textField.innerText = text;
document.body.appendChild(textField);
textField.select();
document.execCommand('copy');
window.clipboardData.setData('Text',copytext);
textField.remove();


函数copytext(text){
var textField = document.createElement('textarea');
textField.innerText = text;
document.body.appendChild(textField);
textField.select();
document.execCommand('copy');
$(textField).remove();
}


解决方案

试试这个。适用于我。

var copy = function(elementId){var input =的document.getElementById(elementId); var isiOSDevice = navigator.userAgent.match(/ ipad | iphone / i); if(isiOSDevice){var editable = input.contentEditable; var readOnly = input.readOnly; input.contentEditable = true; input.readOnly = false; var range = document.createRange(); range.selectNodeContents(输入); var selection = window.getSelection(); selection.removeAllRanges(); selection.addRange(范围); input.setSelectionRange(0,999999); input.contentEditable = editable; input.readOnly = readOnly; } else {input.select(); } document.execCommand('copy');}

< ; input type =textid =foovalue =text to copy/>< button onclick =copy('foo')>复制文本< / button>


I have web application, which is mostly designed to be run on mobile devices. I have one button, which will copy to device clipboard the passed text. I am using javascript for that. My code is working great on all mobile devices, except for iphone and ipad. Anybody knows what can be the problem? Here is my code:

CopyToClipboard = function(text, fallback){
    var $t = $('<textarea />');
    $t.val(text).appendTo('body');
    $t.select();
    document.execCommand('copy');
    $t.remove();
    return true;   
};

I have also tried to go this way, but no result, still not working on iphone

function detectIE() {
    var ua = window.navigator.userAgent;

    var msie = ua.indexOf('MSIE ');
    if (msie > 0) {
        // IE 10 or older => return version number
        return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
    }

    var trident = ua.indexOf('Trident/');
    if (trident > 0) {
        // IE 11 => return version number
        var rv = ua.indexOf('rv:');
        return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
    }

    var edge = ua.indexOf('Edge/');
    if (edge > 0) {
        // IE 12 => return version number
        return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
    }

    // other browser
    return false;
}
function copytext(text) {
    if (detectIE()) {
        window.clipboardData.setData('Text', text);
    }
    var textField = document.createElement('textarea');
    textField.innerText = text;
    document.body.appendChild(textField);
    textField.select();
    document.execCommand('copy');
    window.clipboardData.setData('Text', copytext);
    textField.remove();
}

function copytext(text) {
    var textField = document.createElement('textarea');
    textField.innerText = text;
    document.body.appendChild(textField);
    textField.select();
    document.execCommand('copy');
    $(textField).remove();
}

解决方案

Try this. Works for me.

var copy = function(elementId) {

	var input = document.getElementById(elementId);
	var isiOSDevice = navigator.userAgent.match(/ipad|iphone/i);

	if (isiOSDevice) {
	  
		var editable = input.contentEditable;
		var readOnly = input.readOnly;

		input.contentEditable = true;
		input.readOnly = false;

		var range = document.createRange();
		range.selectNodeContents(input);

		var selection = window.getSelection();
		selection.removeAllRanges();
		selection.addRange(range);

		input.setSelectionRange(0, 999999);
		input.contentEditable = editable;
		input.readOnly = readOnly;

	} else {
	 	input.select();
	}

	document.execCommand('copy');
}

<input type="text" id="foo" value="text to copy" />
<button onclick="copy('foo')">Copy text</button>
