[SOLVED] Select a paragraph with JavaScript (on click)?

Select a paragraph with JavaScript (on click)?

Is it possible to select all the text of an element (e.g., a paragraph <p>) with JavaScript? A lot of people think jQuery .select() would do this, but it does not. It merely triggers an event. Note that DOM objects for <input> elements have a native select() method, but most other elements (such as <output> and <p>) do not.

(Do I need to use content-editable to get this to work?)

Solution

You can use Range.selectNodeContents

document.querySelector('button').addEventListener('click', function(){
    var range = document.createRange();
    var selection = window.getSelection();
    range.selectNodeContents(document.querySelector('p'));
    
    selection.removeAllRanges();
    selection.addRange(range);
});

Hello <p>Select me</p> World
<button id ='btn'>Select text</button>
