domquery | like handy DOM manipulation library

I declared var_valid=['var1']; before the tinymce object and pass in the variable var_valid to variable_valid key in tinymce object. In onSubmit: function (api) {}, I clear the element in var_valid array by var_valid.length = 0; and add in new value to var_valid by var_valid.push('input');. In this way, editor did change variable_valid after user submit the dialog box. Now, when user type new variable ({{input}}),it show in span blue block and when user type the old removed variable({{var1}}) no more show in blue block .But, the old variable that has been inserted into the editor before user submit the dialog box remain in blue block. I add tinymce.triggerSave() after reset and close dialog. This refresh the changes and convert old removed variable that exist on editor to display as {{var1}}.
