点击-复制到剪贴板

Question

<p id="p1"> 
...here is a lot of text (html) mixed with php...

<button onclick="copyToClipboard('#p1')">Copy to clipboard</button>

JS

function copyToClipboard(element) {
  var $temp = $("<input>");
  $("body").append($temp);
  $temp.val($(element).text()).select();
  document.execCommand("copy");
  $temp.remove();
}

当我单击该按钮时，结果将被复制，但没有粗体、下划线、行和其他格式设置。在默认情况下，如何复制它？

Answer 1

假设您的所有样式都是内联的，则需要获取元素的html，而不是文本。类似于：

function copyToClipboard(element) {
  var $temp = $("<input>");
  $("body").append($temp);
  $temp.val($(element).html()).select(); //Note the use of html() rather than text()
  document.execCommand("copy");
  $temp.remove();
}

根据评论编辑：

要将格式复制到Gmail消息体或Word文档之类的内容，您必须实际选择元素作为范围。当您将html内容插入文本区域时，实际上是在复制原始文本。你想做这样的事

function copyToClipboard(element) { //Note, element should be a node rather than a jQuery instance.
    var selection = window.getSelection(), //Get the window selection
        selectData = document.createRange(); //Create a range

        selection.removeAllRanges();  //Clear any currently selected text.
        selectData.selectNodeContents(element); //Add the desired element to the range you want to select.
        selection.addRange(selectData); //Highlight the element (this is the same as dragging your cursor over an element)
        var copyResult = document.execCommand("copy");  //Execute the copy.

        if(copyResult) //was the copy successful?
            selection.removeAllRanges(); //Clear the highlight.
        else
            alert("Your browser does not support clipboard commands, press ctrl+c");
}

尝试html()而不是text()

$temp.val($(element).html()).select();
