Disable A Form For Wrong Entry

[bookish]

Hi! May I ask how to disable a form if in the field for specifying a special diet the person places a special room request. How can the form be disabled if the person places words such as "room", "bedroom", "floor"? The error message should be "Please specify your diet requirement." Thanks in advance for your help.

Hi bookish,

 

Can you use drop-down lists instead of input fields?

You can use Lookup tables with variants of special diets and special room requests.

 

 

You can look for some words in the field with the following code:

<SCRIPT LANGUAGE="JavaScript">
function check_text()
{
var text_for_checking = document.getElementById("InsertRecordtext").value;
var wrong_answer = false;
if (text_for_checking.search("room")!=-1) {wrong_answer = true};
if (text_for_checking.search("floor")!=-1) {wrong_answer = true};
if (wrong_answer)
   {
      alert("Please specify your diet requirement.");
      return false;
   }
}
document.getElementById("caspioform").onsubmit=check_text;
</SCRIPT>

Please, enter the name of your field instead of text in the 

var text_for_checking = document.getElementById("InsertRecordtext").value;

 

You can add as many words as you wish, just copy the line

if (text_for_checking.search("room")!=-1) {wrong_answer = true};

and enter your word instead of "room".

 

To use a Java Script code, please add a Header&Footer element, select the Footer element, then click the Source button, and then enter a code. 

 

I hope it helps.

HI! How would I edit the code if the form is an UPDATE form? Thanks for your help.

Hi bookish,

 

Please change "InsertRecord" to "EditRecord" in the line:

var text_for_checking = document.getElementById("EditRecordtext").value;

You can read Details in the Guide.

I hope, it helps!
