how to check if a field contains backslash using client script

In Javascript, escape character is backslash. So, you need to use 2 black slashes in this case. Then, you can use indexOf javascript function to check whether value has blackslash or not.

var fieldvalue = g_form.getValue('fieldname');
if(fieldValue.indexOf('\\') >= 0)
       alert("Field value has black slash.")

var pattern=/\\/;
alert(pattern.test(newValue));
 

if(pattern.test(newValue) )

{
          alert('Backslash presnt);

          g_form.setValue('u_urfieldname', '');

  }

That's great. Check this, if you want to use reg. ex

var fieldvalue = g_form.getValue('fieldname');  

var reg=/\b\\/g;

if(fieldvalue.match(reg))  

    alert("Field value has black slash.")
