title: Jquery remove text from span
body: <p>I'm new to JQuery and really struggling how to perform the query I want.</p>
  
  <p>I'm using SharePoint, and the when using the External Data Column and set it to required field, the error message always appears until you fill in the data. Unlike other type columns where they only appear after you click OK/Save and not filled in the data. Therefore I need to remove the error message text just from these type of columns.</p>
  
  <p>I assume I need to search for span within the .ms-error class that contains the words 'External Data' and hide it.</p>
  
  <p>From using IE developer toolbar, I've identified the area.</p>
  
  <pre><code> &lt;table class="ms-usereditor" id="ctl00_m_g_05df537a_596b_443a_a11e_764069facec8_ctl00_Field_External_539c53fe_8334_43c8_b089_cc28d7895e68_Picker_OuterTable" style="border-collapse: collapse;" border="0" cellSpacing="0" cellPadding="0"&gt;
      &lt;tbody&gt;
       &lt;tr&gt;
       &lt;td colSpan="3"&gt;
         &lt;span class="ms-error" id="ctl00_m_g_05df537a_596b_443a_a11e_764069facec8_ctl00_Field_External_539c53fe_8334_43c8_b089_cc28d7895e68_Picker_errorLabel"&gt;
             Text - You must specify a value before using the Check button. You can also use Select button to choose External Data.
          &lt;/span&gt;
        &lt;/td&gt;
        &lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Please can someone help me with the JQuery. </p>
