validation in javascript - remove the error msg on focus
- by fusion
i'm not very well-versed with javascript, so please bear with me.
i've a form in which i validate the controls with javascript. the error is displayed when the fields are empty via a div, but when i focus and type something in the textbox, the div should go away. but the error div doesn't and even if i type something valid, it still displays the div.
i'd like to know where am i going wrong with this script:
<script type="text/javascript">
var err = document.getElementById("errmsg");
function checkInput(inPut) {
if (inPut.getValue() == "") {
err.setStyle('display', 'block');
err.setTextValue("Field cannot be empty!");
inPut.focus();
return false;
}
else {
return true;
}
}
function checkTextBox(textBox)
{
if (textBox.getValue() == "") {
err.setStyle('display', 'block');
err.setTextValue("Field cannot be empty!");
textBox.focus();
return false;
}
else if (!checkValidity(textBox.getValue())) {
err.setStyle('display', 'block');
err.setTextValue("Please enter a valid email address!");
textBox.focus();
return false;
}
else {
return true;
}
}
. . .
<div id="errmsg" class="invalid" style="display:none;"></div> <br />
. . .
<input type="text" tabindex="1" name="name" id="name" class="input_contact" onblur="checkInput(this);"/> <br />
. . .
<input type="text" tabindex="2" name="email" id="email" class="input_contact" onblur="checkTextBox(this);"/> <br />
it's a form in facebook app but while the fbjs works, i assume there's a problem with my basic javascript.
