Question

我正在创建一个Phonegap应用，要求用户在p元素中选择文字，然后＆＃34;复制＆＃34;修改它的文本需要。

但是，在p标记内选择文字时出现问题。从我的服务器检索文本，其中输出如下：

<p style="white-space:pre-wrap">Proin quis tortor orci. Etiam at risus et justo dignissim congue. Donec congue lacinia dui, a porttitor lectus condimentum laoreet. Nunc eu ullamcorper orci. Quisque eget odio ac lectus 


vestibulum faucibus eget in metus. In pellentesque faucibus vestibulum. Nulla at nulla justo, eget luctus tortor. Nulla facilisi. 

Duis aliquet egestas purus in blandit. Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu ad litora
</p>

这将使文本保留换行符，而不使用<br/>标记，这些标记目前在我的Javascript中无效。

无论如何，当您尝试在此元素中选择文本时，将选择整个p元素。这是选择单词时发生的转换，然后移动边界以选择更多文本：

注意：第一个序列中的文字不同，因为我用不同的文字截取屏幕截图，但效果仍然相同。

我无法为此提供jsFiddle，因为它似乎只在Phonegap中复制，但我已将我的来源上传到测试：http://cl.ly/2w0O1d3l3h17

项目中没有JS，但HTML和CSS看起来像这样：

HTML：

        Electronic Fill-In-The-Blank PDF Forms
        NOTE: Use of PDF fill-in-the-blank forms does NOT include online
        submittal.
        Some PDF forms are available in a fill-in-the-blank format. Users now have
        the option—on certain OPA forms—to complete the PDF forms
        electronically, instead of manually writing or typing the information on a hard
        copy version.
        The form can be completed in several easy steps.
        q The user opens the PDF form in Acrobat Reader—in the browser or as
        a standalone product. The user can also save the PDF form to their
        computer system and open the form in Acrobat Reader at a later time.

        blinking cursor appears.
        After the information has been entered in the field, the user can tab to
        the next field.
        After all the fields have been completed, the user can print out the
        page.
        NOTE: If the cursor is blinking in a field, the information in that field
        will not be printed. Hit "Return" or "Enter" and the information will be
        captured for all fields.

        Users with Acrobat Reader only, the entered data cannot be saved for later
        use.
        For those who have the entire Acrobat suite—Acrobat, formerly called
        Acrobat Exchange—the data can either be saved separately or as a part of the
        form. If you save the data-only, it will take up less disk space and can be
        imported back into the same form at any time, provided the form has not
        changed. For more information on exporting and importing form data, check
        your manual.

CSS：

.text{
    white-space:pre-wrap;
    word-wrap: break-word;
    height:300px;
    overflow: scroll;
    -webkit-overflow-scrolling: touch;
    padding:10px;
    border:1px solid #000;
    background-color:#fff;
}

我发现的一个潜在解决方案是在contenteditable="true"元素上使用p，但这有一些缺陷：

我不能在元素
我无法显示键盘

我发现的另一个解决方案是删除pre格式。但是，这会删除换行符，我希望保留换行符。

Answer 1

你的问题是iOS的原生选择引擎选择单独的单词或整个元素。并且因为您有一个<p>元素保存整个文本，所以当您尝试选择多行时，本机选择引擎会选择整个<p>元素。你应该做的是“提示”你想要能够选择多行的选择引擎。您可以通过将每行文字放入单独的block level element来实现这一目标，例如<div>。

这是一个示例脚本，用于解析<p class="text">元素内的文本，并将每行文本放入单独的<div>元素中，通过使用每行开头保留新行，空行和空格non-breaking-space个字符实体。

var textElm = document.getElementsByClassName("text")[0],
    text = textElm.textContent,
    html = "";

html = text.replace(/([\t ]*)(.*)\n/g, function(match, spaces, text) {
    if (spaces === "" && text === "") spaces = " "; // Make sure empty lines are rendered by adding single &nbsp; to <div>
    return "<div>" + Array(spaces.length + 1).join("&nbsp;") + text + "</div>"
});

textElm.innerHTML = html;

enter image description here

然后您也可以从CSS中删除white-space:pre-wrap;，因为不再需要它。

Answer 2

对此的解决方案是将整个内容放在p标记或任何内容中，然后将通常由<br />分隔的每个段落与看起来像的假线中断分开像这样：

<a class="space"></a>

它可以是任何正常的内联元素，然后我们将以下CSS给出：

.space{
    display:inline-block;
    height:15px;
    width:100%;
}
