Question

Validating a form is not working. Below you see the code and error message.
Don’t think its a problem with JS, Chrome and Firefox point to the HTML part.
See screenshot I made from Firefox’ Firebug.

HTML:

<div>Enter your state code:<input id="state" name="state" type="text" size="2" onblur="isStateOk(this.document.getElementById("state_help"));"/>        
<span id="state_help"></span></div> 

Javascript:

function isStateOk(inputField, helpId) {        // See if the input value contains any text

    return editNodeText (/^A[LKSZRAEP]|C[AOT]|D[EC]|F[LM]|G[AU]|HI|I[ADLN]|K[SY]|LA|M[ADEHINOPST]|N[CDEHJMVY]|O[HKR]|P[ARW]|RI|S[CD]|T[NX]|UT|V[AIT]|W[AIVY]$/, inputField.value, helpId, "Enter a State Code in Uppercase (Ex.NY, PA, CA)");
}

Note: eclipse show a red dotted line under: (“state_help“). Maybe the id of the span cannot be found at all? I do get code assistance though when start typing state_

UPDATE: JAVASCRIPT FILE: NEW ERROR MESSAGE POINTING TO THE FIRST FUNCTION IN THIS FILE BELOW:

function editNodeText(regex, input, helpId, helpMessage) {        // See if the visitor entered the right information

    if (!regex.test(input)) {          // If the wrong information was entered, warn them

        if (helpId != null)

            while (helpId.firstChild) // Remove any warnings that may exist

                helpId.removeChild(helpId.firstChild);

                helpId.appendChild(document.createTextNode(helpMessage)); // Add new warning

                return false;
    } else {          // If the right information was entered, clear the help message

        if (helpId != null){

            while (helpId.firstChild) // Remove any warnings that may exist

                helpId.removeChild(helpId.firstChild);
        }

        return true;

    }   
}




//inputField – ID Number for the html text box

function isTheFieldEmpty(inputField, helpId) {

}

}



function isPhoneOk(inputField, helpId) {        // See if the input value contains any text

    return editNodeText(/^([0-9]( |-)?)?(\(?[0-9]{3}\)?|[0-9]{3})( |-)?([0-9]{3}( |-)?[0-9]{4}|[a-zA-Z0-9]{7})$/, inputField.value, helpId, "Enter a Phone Number (Ex.412-828-3000)");

function isEmailOk(inputField, helpId) {        // See if the input value contains any text

    return editNodeText(/^[A-Za-z0-9._-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/, inputField.value, helpId, "Enter an Email (Ex. [e-mail])");

}

Answer 1

Use single quotes for JS strings contained within an html attribute’s double quotes or the result is unparseable;

From:

onblur="isStateOk(this.document.getElementById("state_help"));"/>

to:

onblur="isStateOk(this.document.getElementById('state_help'));"/>
