appliquer le style avec execCommand le texte arbitraire

Question

Je sais comment exécuter execCommand sur un texte sélectionné, mais est-il un moyen d'exécuter sur un autre texte dans mon contenteditable div?

Answer 1

In IE, yes. In other browsers, no.

All major desktop browsers implement some form of document.execCommand(), which acts only on the user selection. In IE, the TextRange object also has an execCommand method. For example, the following will turn the text contents of an element green when the user hovers the cursor over it:

<div id="test">Here is a test div</div>

<script type="text/javascript">
    var div = document.getElementById("test");
    div.onmouseover = function() {
        if (document.body.createTextRange) {
            var textRange = document.body.createTextRange();
            textRange.moveToElementText(div);
            textRange.execCommand("foreColor", false, "green");
        }
    };
</script>

In case you are not aware, the .execCommand is an IE only non-standard javascript function that should be avoided.

If you tell us what you want to use it for, then we could suggest a standards-compliant alternative.
