JS

  var $temp = $("<input>");
  $("body").append($temp);

  document.execCommand("copy");
  $temp.remove();
}

当我点击按钮时，结果被复制但没有粗体、下划线、行和其他格式化内容。 默认情况下如何复制它？

Answer 1

假设您所有的样式都是内联的，您需要获取元素的 html 而不是文本。像这样的东西:

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 邮件正文或 Word 文档中，您必须实际选择该元素作为范围。当您将 html 内容插入文本区域时，您实际上是在复制原始文本。你想做这样的事情:

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");
}
