I am using TinyMCE for <textarea>. My requirement is to limit the character size to 2000 and also to show the remaining characters somewhere below the tool bar. I somehow managed to get the characters number; now I am stuck with displaying the remaining characters and prevent from exceeding limit.
Here is my TinyMCE code
tinyMCE.init({
// General options
mode : "textareas",
theme : "simple",
plugins : "autolink,lists,pagebreak,style,table,save,advhr,advimage,
advlink,emotions,media,noneditable,visualchars,nonbreaking,
xhtmlxtras,template",
// Theme options
theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,
justifyleft,justifycenter,justifyright,
justifyfull,|,styleselect,formatselect,
fontselect,fontsizeselect",
theme_advanced_buttons2 : "bullist,numlist,|,outdent,indent,|,undo,redo,|,
link,unlink,anchor,image,code,|,forecolor,
backcolor",
theme_advanced_toolbar_location : "top",
theme_advanced_toolbar_align : "left",
theme_advanced_statusbar_location : "bottom",
theme_advanced_resizing : true,
charLimit : 10, // this is a default value which can get modified later
setup : function(ed) {
//peform this action every time a key is pressed
ed.onKeyUp.add(function(ed, e) {
//define local variables
var tinymax, tinylen, htmlcount;
//manually setting our max character limit
tinymax = ed.settings.charLimit;
//grabbing the length of the curent editors content
tinylen = ed.getContent().replace(/(<([^>]+)>)/ig,"").length;
//setting up the text string that will display in the path area
htmlcount = "HTML Character Count: " + tinylen + "/" + tinymax;
//if the user has exceeded the max turn the path bar red.
if (tinylen>tinymax){
}
});
}
});
For testing purpose I am trying to limit up to 10 char.
Any suggestions are welcome.

Reset to default 9I suggest you execute your code onKeyDown, because on KeyUp the letter is already in the editor.
//peform this action every time a key is pressed
ed.onKeyDown.add(function(ed, e) {
//define local variables
var tinymax, tinylen, htmlcount;
//manually setting our max character limit
tinymax = ed.settings.charLimit;
//grabbing the length of the curent editors content
tinylen = ed.getContent().replace(/(<([^>]+)>)/ig,"").length;
//setting up the text string that will display in the path area
htmlcount = "HTML Character Count: " + tinylen + "/" + tinymax;
//if the user has exceeded the max turn the path bar red.
if (tinylen > tinymax){
// place text string in path bar
if ( $('#max_char_string').size() ){
$('#max_char_string').html( ' ' + htmlcount);
}
else {
$("div#"+ed.id+"_path_row").append('<span id="max_char_string"> '+htmlcount+'</span>')
}
// prevent insertion of typed character
e.preventDefault();
e.stopPropagation();
return false;
}
I had the same issue and found this link very useful: http://www.ryann.ca/?p=186
Although I changed this slightly so that it reads the attribute of maxlength direct from the textarea.
tinyMCE.init({
// Options
setup : function(ed) {
ed.onKeyUp.add(function(ed, e) {
var tinylen, htmlcount, maxlength = $("#" + tinyMCE.activeEditor.id).attr("maxlength");
if (maxlength) {
// grabbing the length of the curent editors content
tinylen = ed.getContent().length;
htmlcount = "HTML Character Count: " + tinylen + "/" + maxlength;
if (tinylen > maxlength) {
htmlcount = "<span style='font-weight:bold; color: #f00;'>" + htmlcount + "</span>";
}
// write the html count into the path row of the active editor
tinymce.DOM.setHTML(tinymce.DOM.get(tinyMCE.activeEditor.id+ '_path_row'), htmlcount);
}
});//ed.onKeyUp.add
}//setup
});
Hope it will work :)
setup: function(ed) {
var maxlength = parseInt($('#'+(ed.id)).attr("maxlength"));
var count = 0;
ed.on('keydown', function(e) {
count++;
if (count >= maxlength)
{
alert("false");
return false;
}
});
},
