Selecting text in an element (akin to highlighting with your mouse)


I would like to have users click a link, then it selects the HTML text in another element (not an input).

By "select" I mean the same way you would select text by dragging your mouse over it. This has been a bear to research because everyone talks about "select" or "highlight" in other terms.

Is this possible? My code so far:

HTML:

<a href="javascript:" onclick="SelectText('xhtml-code')">Select Code</a>
<code id="xhtml-code">Some Code here </code>

JS:

function SelectText(element) {
    $("#" + element).select();
}

Am I missing something blatantly obvious?


Solution

  • Plain Javascript

    function selectText(nodeId) {
        const node = document.getElementById(nodeId);
    
        if (document.body.createTextRange) {
            const range = document.body.createTextRange();
            range.moveToElementText(node);
            range.select();
        } else if (window.getSelection) {
            const selection = window.getSelection();
            const range = document.createRange();
            range.selectNodeContents(node);
            selection.removeAllRanges();
            selection.addRange(range);
        } else {
            console.warn("Could not select text in node: Unsupported browser.");
        }
    }
    
    const clickable = document.querySelector('.click-me');
    clickable.addEventListener('click', () => selectText('target'));
    <div id="target"><p>Some text goes here!</p><p>Moar text!</p></div>
    <p class="click-me">Click me!</p>

    Here is a working demo. For those of you looking for a jQuery plugin, I made one of those too.


    jQuery (original answer)

    I have found a solution for this in this thread. I was able to modify the info given and mix it with a bit of jQuery to create a totally awesome function to select the text in any element, regardless of browser:

    function SelectText(element) {
        var text = document.getElementById(element);
        if ($.browser.msie) {
            var range = document.body.createTextRange();
            range.moveToElementText(text);
            range.select();
        } else if ($.browser.mozilla || $.browser.opera) {
            var selection = window.getSelection();
            var range = document.createRange();
            range.selectNodeContents(text);
            selection.removeAllRanges();
            selection.addRange(range);
        } else if ($.browser.safari) {
            var selection = window.getSelection();
            selection.setBaseAndExtent(text, 0, text, 1);
        }
    }
