我工作的一个Web应用程序，允许用户选择一些文本，点击一个按钮，并保存突出显示的文本。这个工作在桌面浏览器大，（铬在这个例子中），但在iOS的我在与本地文本选择，用户可以更改所选文本的问题。

这里是的jsfiddle显示问题（问题只存在于iOS版）： http://jsfiddle.net/JasonMore/gWZfb/

用户启动文本选择
用户扩展了他们的文本选择，并点击“显示上面选定的文本”
只有第一个选择的单词“the”显示出来，即使我想“ 义人的道路 ”

1开始

2选择文本，然后按按钮

3只有“”

下面是我使用的JS：

$(function() {
    $('#actionButton').click(function() {
        $('#result').text(selectedRange.toString());
    });

    $('#slipsum').on('mouseup touchend','p', function() { 
        getSelectedRange();
    });
});

var selectedRange = null;

var getSelectedRange = function() {
    if (window.getSelection) {
        selectedRange = window.getSelection().getRangeAt(0);
    } else {
        selectedRange = document.getSelection().getRangeAt(0);
    }
};

HTML：

<h3>Selected Text:</h3>
<p id="result">
</p>
<br/>
<p>
    <input type="button" id="actionButton" value="Show the selected text above" />
</p>
<!-- start slipsum code -->
<div id="slipsum">
<h1>Is she dead, yes or no?</h1>
<p>Do you see any Teletubbies in here? Do you see a slender plastic tag clipped to my shirt with my name printed on it? Do you see a little Asian child with a blank expression on his face sitting outside on a mechanical helicopter that shakes when you put quarters in it? No? Well, that's what you see at a toy store. And you must think you're in a toy store, because you're here shopping for an infant named Jeb. </p>

<h1>So, you cold?</h1>
<p>The path of the righteous man is beset on all sides by the iniquities of the selfish and the tyranny of evil men. Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy My brothers. And you will know My name is the Lord when I lay My vengeance upon thee. </p>

<h1>I'm serious as a heart attack</h1>
<p>Do you see any Teletubbies in here? Do you see a slender plastic tag clipped to my shirt with my name printed on it? Do you see a little Asian child with a blank expression on his face sitting outside on a mechanical helicopter that shakes when you put quarters in it? No? Well, that's what you see at a toy store. And you must think you're in a toy store, because you're here shopping for an infant named Jeb. </p>

<h1>Is she dead, yes or no?</h1>
<p>Like you, I used to think the world was this great place where everybody lived by the same standards I did, then some kid with a nail showed me I was living in his world, a world where chaos rules not order, a world where righteousness is not rewarded. That's Cesar's world, and if you're not willing to play by his rules, then you're gonna have to pay the price. </p>

<h1>Is she dead, yes or no?</h1>
<p>Your bones don't break, mine do. That's clear. Your cells react to bacteria and viruses differently than mine. You don't get sick, I do. That's also clear. But for some reason, you and I react the exact same way to water. We swallow it too fast, we choke. We get some in our lungs, we drown. However unreal it may seem, we are connected, you and I. We're on the same curve, just on opposite ends. </p>

任何人谁在这个问题在未来绊倒，这里是该决议：

http://jsfiddle.net/JasonMore/gWZfb/

$(function() {
    $('#actionButton').click(function() {
        if (selectedRange) {
            $('#result').text(selectedRange.toString());
            clearInterval(timer);
        }
    });

    timer = setInterval(getSelectedRange, 150);
});

var timer = null;

var selectedRange = null;

var getSelectedRange = function() {
    try {
        if (window.getSelection) {
            selectedRange = window.getSelection().getRangeAt(0);
        } else {
            selectedRange = document.getSelection().getRangeAt(0);
        }
    } catch (err) {

    }

};
