title: Changing the color of particular words in Textareafield in Sencha Touch
body: <p>I want to change the font color of the misspelled words in a Textareafield in Sencha Touch2. I have the array of misspelled words.
  This is the textareafield.</p>
  
  <pre><code>           {
                  xtype:'textareafield',
                  label:'Note',
                  id:'txt',
                  scroll:'vertical',
  
              },
  </code></pre>
  
  <p>MisspeltArr will have the wrongly spelt words.</p>
  
  <pre><code>                    var misspeltArr =[];
                      for(i = 0;i&lt;txtArr.length;i++){
                          var spellCheck = dictionary.check(txtArr[i]);
                          console.log("spellCheck : "+spellCheck);
                          if(spellCheck == false){
                              misspeltArr.push(txtArr[i]);
                          }
                      }
  </code></pre>
  
  <p>Say i have typed the below text in the textareafield, </p>
  
  <pre><code>   Thisss is a mobile application screennn
  </code></pre>
  
  <p>Now in txt I have the text entered</p>
  
  <pre><code>  var txt = Ext.getCmp('txt').getValue();
  </code></pre>
  
  <p>I want to change the color or underline the wrong words - Thisss and screennn (words in the array) in the textareafield. I have achieved spell check and all I want to do is Highlighting the wrong words. Any help is appreciated.</p>
