Hello,

Please check if this helps.

Try this onchange catalog client script.

function onChange(control, oldValue, newValue, isLoading) {

  if(isLoading || newValue == ''){

          return;

  }

var pattern = /^[0-9a-zA-Z]*$/;

    if(!pattern.test(newValue))

    {

          alert('type your appropriate comments here');

          g_form.setValue('variable_name', ''); // adjust field name accordingly if you want to blank it out.

  }

}

Hello Shishir,

Following is the script which I am currently using

function onSubmit() {

    //Type appropriate comment here, and begin script below

    var alpha = new RegExp("^[a-zA-Z0-9]*$");

  var BusinessCase=g_form.getValue('justification');

  //alert("value"+BusinessCase);

  var res=alpha.test(BusinessCase);

  if (!res) {

          // g_form.showFieldMsg('justification', 'Invalid input', 'error');

alert ("Special Charecters are not allowed on Justification");

return false;

  }

return;

}

This script do not allows "Space" in the string field

Could you please tell me what changes needs to be done in current script in order to run this if statement containes spaces

Dear All,

I have finalised my script as follows

this works for restricting special character as well as allowing spaces in between

function onSubmit() {

// Type appropriate comment here, and begin script below

    //var alpha = new RegExp("^[a-zA-Z0-9]*$");

var alpha = /^[\s0-9a-zA-Z]*$/;

  var BusinessCase=g_form.getValue('justification');

  //alert("value"+BusinessCase);

  var res=alpha.test(BusinessCase);

  if (!res) {

            //g_form.showFieldMsg('justification', 'Invalid input', 'error');

alert ("Special Charecters are not allowed on Business Case / Justification field");

return false;

  }

return;

}
