Javascript - How can I retrive the Character count?

Reply Quote

I can see the Character count listed in the bottom but cannot figure out how extract that number.

I've tried a regex filter but it's usually off 5 characters or so to what is being displayed in the bottom bar.

Please use the following method to extract the html code from editor. Then get the count of this string.

getHTML()

This method is used for retrieving the content of CuteEditor as HTML.

Example:

// get the cute editor instance
var editor1 = document.getElementById('CE_Editor1_ID');

// retrieving the content of Cute Editor as HTML
var content = editor1.getHTML();
alert(content );

I guess I didn't explain myself very well I went down the 'getHTML' route. :)

function chkTxtLength() {

reTag = /(<([^>]+)>)/ig;

contentVar = editor1.getHTML();

contentVar = contentVar.replace(reTag, "");

return contentVar.length;

}

The number outputted by the above function is usually off by about 5 characters give or take.

I figure why reinvent the wheel, the character count is sitting in the right lower right hand corner.

That had to come from somewhere, how do retrieve it or what's the regex they use?

Actually this turns out to be 1000 for characters off in the right copy and paste situation.

Once again how can it just pull the value that is already calculated in the bottom corner?

Getting and RegEx-ing to get an already rendered count seem stupid.

Any ideas how to do this right?

Back to my solo conversation I figured out another way to do it...

function getCount() {

var cnt = getElementsByClass('CharCount',document.getElementById("CE_Editor1_ID"),"span");

cnt = (cnt[0].innerHTML.replace("Characters:","")*1)

alert(cnt+100);

}

function getElementsByClass(searchClass,node,tag) {

var classElements = new Array();

if ( node == null )

node = document;

if ( tag == null )

tag = '*';

var els = node.getElementsByTagName(tag);

var elsLen = els.length;

var pattern = new RegExp("(^|\\s)"+searchClass+"(\\s|$)");

for (i = 0, j = 0; i < elsLen; i++) {

if ( pattern.test(els[i].className) ) {

classElements[j] = els[i];

j++;

}

return classElements;

}
