使用jQuery select（）选择div的内容 [英] Use jQuery select() to select contents of a div

问题描述

是否可以使用或调整jQuery的.select（）来设置div的整个内容的选择范围？

Is it possible to use or adapt jQuery's .select() to set a selection range on the entire contents of a div?

我有一个div有一个div一系列标签，输入，选择对象和一些其他UI元素。我在一个单独的StackOverflow帖子上找到了代码，其中一些代码托管在jsFiddle上： http://jsfiddle.net/KcX6A/ 570 /

I have a div which has a series of labels, inputs, select objects and a couple of other UI elements. I have found code on a separate StackOverflow post with some code hosted on jsFiddle: http://jsfiddle.net/KcX6A/570/

是否可以调整以选择输入值？或者您会如何建议我这样做？

Can this be adapted to select the value of inputs also? Or how would you suggest I go about this?

谢谢，

Thanks, Conor

我知道如何使用jQuery获取输入值，这很简单，我也知道如何选择他使用.select（）的独立元素的值。

I know how to get the value of inputs using jQuery, that is easy, I also know how to select he values of independent elements using .select().

在我的div中，我有一系列不同的元素类型，包括输入，标签，选择等。我需要一个整体选择所有元素。我之前添加的jsFiddle链接显示了如何设置div的范围并选择像p标签等元素的文本。我需要的是设置div的内容范围，当我点击ctrl + c或cmd + c时复制输入的值以及标签。

In my div I have a series of different element types including inputs, labels, selects, etc. I need an overall selection of all elements. The jsFiddle link I added earlier shows how to set the range of a div and select the text of elements like p tags etc. What I need is to set the range of the div's contents and when I hit ctrl+c or cmd+c it copies the values of the inputs as well as the labels.

总而言之，使用.val和.select将不起作用，我不这么认为。我需要以某种方式结合上述内容，但不确定如何实现。任何想法？

So to summarise, using .val and .select won't work for this I don't think. I need to combine the above in some way but not sure exactly how this will be accomplished. Any ideas?

基本上诀窍是引入一个隐藏文本节点，其内容将在复制时包含在选择中。

Basically the trick is to introduce a hidden text node whose content will be included in the selection when copied.

jQuery.fn.selectText = function(){
    this.find('input').each(function() {
        if($(this).prev().length == 0 || !$(this).prev().hasClass('p_copy')) { 
            $('<p class="p_copy" style="position: absolute; z-index: -1;"></p>').insertBefore($(this));
        }
        $(this).prev().html($(this).val());
    });
    var doc = document;
    var element = this[0];
    console.log(this, element);
    if (doc.body.createTextRange) {
        var range = document.body.createTextRange();
        range.moveToElementText(element);
        range.select();
    } else if (window.getSelection) {
        var selection = window.getSelection();        
        var range = document.createRange();
        range.selectNodeContents(element);
        selection.removeAllRanges();
        selection.addRange(range);
    }
};

并使用它：

$('#selectme').selectText();

您可以将上述插件与事件处理程序结合使用如果你想创建选择链接：

You can couple the above plugin with an event handler if you want to create selection links :

代码：

$('.select-text').on('click', function(e) {
    var selector = $(this).data('selector');
    $(selector).selectText();
    e.preventDefault();
});

用法：

<a href="#" class="select-text" data-selector="#some-container">Select all</a>
<div id="some-container">some text</div>
