Inserting at the cursor using JavaScript

Inserting at the cursor using JavaScript
NOTE:I’ve released a set of JavaScript Quicktags(that implement this technique)under the LG PL license.Please look at has a variety of enhancements and bug fixs.
I discovered a real JavaScript gem in PHPMyAdmin this moning.They have code that inserts content into aa t the cursor position instead of just/end of the content.This sothatwable.<br>I’ll be glad to see this code spread quickly to web forms that use buttons to aid in styling text and inserting image and link tags.WodPress and web forum package world relybenefit from GPhers.put<br>Here is a quick look at a generic version of the technique:<code>function insertAtCursor(myField, myValue) {<br/> //IE support<br/> if (document.selection) {<br/> myField.focus();<br/> sel = document.selection.createRange();<br/> sel.text = myValue;<br/> }<br/> //MOZILLA/NETSCAPE support<br/> else if (myField.selectionStart || myField.selectionStart == '0') {<br/> var startPos = myField.selectionStart;<br/> var endPos = myField.selectionEnd;<br/> myField.value = myField.value.substring(0, startPos)<br/> + myValue<br/> + myField.value.substring(endPos, myField.value.length);<br/> } else {<br/> myField.value += myValue;<br/> }<br/> }<br/> // calling the function<br/> insertAtCursor(document.formName.fieldName, 'this value');</code>I gusess when the mouse leaves the textarea、it still has a cursor position left over.This code uses that position just'd want it to.
