ckeditor validation for spaces -


How can I apply verification to ckeditor to prevent the user from simply adding spaces

Of the following, I've tried verification: 

  // ckeditor $ ("Save note from input .save_note"). Click (function () {var note_ id1 = $ (this) .attr ("rel"); var thiss1 = this; var profile_user_id = $ (this) .attr ("rel1"); var txt = ckeditor.instances.editor1 .getData (); var no_space_txt = txt.replace ("& amp; nbsp;", ""); // var txt = txt1.replace (/ + (? =) / G, ''); var editor_val1 = CKEDITOR .instances.editor1.document.getBody (). GetChild (0) .gettext (); var editor_val = editor_val1.replace (/ + (? =) / G, ''); // if (editor_val == "") // {// warning ('sak'); // return; // if (editor_val! == "" & amp; editor_val! == "") {$ (this) .attr ("(" URL " , "Disabled"); var loading_emg = ad loading image ($ (this), "before"); jQuery.ajax ({url: "/" + PROJECT_NAME + "profile / save-note-" editor ", type:" Post ", data release : "Jason", data: {"profile_user_id": profile_user_id, "note": txt}, expiration: 50000, success: function (JSData) {if (jsonData) {$ ("P # clickable_note _" + note_id1). Hide (); $ (Thiss1) .hide ();. $ (Thiss1) .siblings ("input.edit_note") fadein (); $ ("duration #" + loading_img) .remove (); . Deleting $ (".warning-box"); . $ ("Notice-box1") removal (); . Deleting $ (". Info-box2"); ShowDefaultMsg ("note saved successfully.", 1); $ (Thiss1) .removeAttr ('Disabled'); // $ (".cke_inner cke_reset"). Hide (); CKEDITOR.instances.editor1.destroy (); Hide $ (".Press1"). $ ("P # clickable_note _" + note_id1) .html (jsonData) to display saved notes in clickable p tags; // $ ("P # clickable_note _" + note_id1) FadeIn ('slow'); // Note after editing and saving the notes to display the paragraph. } And {$ (thiss1) .removeAttr ('disabled'); $ (Thiss1) Before ('& lt; span class = "spanmsg" id = "note-msg" style = "color: red;" & gt; server error ;); }}, Error: work (xhr, ajaxOptions, thrownError) {warning (thrownError + "\ r \ n" + xhr.statusText + "\ r \ n" + xhr.responseText); }}); } And {warnings ("You can not create blank notes, please enter some text."); }});

I have applied the warning to check that no text has been entered but I want to know whether the user is just entering the blank space or not. Please suggest some exact way.

Since you're clearly using jQuery, you add it as An additional check for your situation: 

  jQuery.trim (editor_val) .length! = 0

This will trim all the submitted space and will check whether there is any remaining balance if the input is only of white space, the statement false . You will integrate it into the following line: 

  if (editor_val! = "" & Amp; amp; amp; editor_value! = "" & Amp; amp; amp; amp; amp; amp; jQuery.trim (editor_val) Length! = 0)

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
