I am using TinyMCE for . My requirement is to limit the character size to 2000 and also to show the remaining characters somewhere below the tool ba
I 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 {
$("div#"+ed.id+"_path_row").append('<span id="max_char_string"> '+htmlcount+'</span>')
}
// prevent insertion of typed character
e.preventDefault();
e.stopPropagation();
return false;
}
Hope it will work :)
setup: function(ed) {
var maxlength = parseInt($('#'+(ed.id)).attr("maxlength"));
var count = 0;
ed.on('keydown', function(e) {
count++;
if (count >= maxlength)
{
alert("false");
return false;
}
});
},
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
});
