Question

In my rails application ,iam using jqgrid to enter data in rows.there is a description box which allows certain no of characters.The problem here is i can drag and drop images and urls which the description box accepts.How can i prevent it.
here is the short code i have taken out from the main after some edit..

  $(document).ready(function() {

     colNamesData = [ 'Description', 'Hours']
     colModelHash = [ 
     {name:'description',index:'description', width:130,sorttype:"text", editable:true, edittype:"textarea", editoptions: {rows:"5",cols:"25",maxlength:"255"}, stype:'text'},
     {name:'hours',index:'hours', width:130, align:'center',editable:true, edittype:"select",editoptions:{value:"<%= hours_options %>"}, search:true, stype:'text'}
                      },
          ]
   $("#data_table").jqGrid({
      datatype: "local", 
      height: "auto",
      autowidth: true,
      ignoreCase: true,
      colNames: colNamesData, 
      colModel: colModelHash,
      pager: '#pager',
      rowNum:10,
      rowList:[10,25,50,100],
      sortname: 'hours',
      sortorder: 'desc',
      viewrecords: true,
      editurl:"/data_call.json", 
      caption: 'My info',

     },
      data:<%= raw @data_jqgrid_date.to_json %>
   });

   jQuery("#data_table").jqGrid('navGrid','#pager',{del:false,add:true,edit:false},{}, {}, {});  
   var details =  <%= raw @details.to_json %>

In my view you can have a JavaScript method.
Just bind the change method of that text box with the method.
Check the value, if it contains any invalid character then reset it to balnk(”) and return false.
