When a user has entered text into form fields and hits the Save button, the text is saved into local storage. When they hit the Load button at a later date, the text fields are populated.If the user does NOT enter text and hits the Load button, the default empty text fields are populated with the word "undefined." How do I keep the field blank? Because if they do this accidentally, they'll be hitting the back button repeatedly to delete the word in every field (this is on an iPhone).Here is the Load code:
Code:
/*
* Insert data into form fields from local storage.
I am trying to create a javascript form validation that will make a text field be required only if a previous text field is populated. If the first text field is blank, then the second field can be blank as well.
what's wrong with this code to check if a text field is blank and either display/hide the <div> accordingly.
Code: <SCRIPT language=javascript type=text/javascript> function validateForm(order) { {
[Code]....
The <div> (id='name') is displayed if nothing is entered and the user clicks submit, however if the user then enters a value into the text field, and re-submits, the <div> still appears.
I'm trying to set up a form that has a text field that is required to be blank - I'm dealing with form spam, and the bots are stuffing every text field with random crap. So, I have a text box that is required to be blank. But I can't get jquery.validate to understand both required and blank.the text input is has a name and id of live_check.I have added this method:
$.validator.addMethod("equalToParam", function(value, element, param) {return value == param;});
The following code is my form, if one of the fields is left blank (and there will usually be one left blank) the calculation returns NaN and will not perform the task needed. I initially had the form set to calculate in metric kilometers and liters, when I converted the math portion to miles and gallons it started doing this.This is the line giving me the problems:
var cars_emissions=(((mileage1/efficiency1)*0.3732417216/1000)+((mileage2/efficiency2)*0.3732417216/1000)+((mileage3/efficiency3)*0.3732417216/1000)); The original was:
I have a three field contact form on an HTML5 page. Using CSS3/HTML5 techniques, the fields change state as the info is entered properly (green OK symbol if good, red "!" if not, etc). That all works as expected in all browsers.
My final hurdle is preventing the form being submitted with nothing entered in the fields. I have done hours of research and have tried several ways of writing the checkFeedbackForm function. My problem is that none of the solutions I've found are recognized by FireFox (mac and pc) and IE. They just ignore the javascript and allow the empty form to be emailed.
My Javascript doesn't display an error when the "bid" field is blank but I want it to.Everything else works okay but I'm not a Javascript programmer so I don't know where to begin.
function checkBid(fieldName,minValue,maxValue){ var numberfield = fieldName; if (chkNumeric(fieldName,minValue,maxValue) == false){
I want to carry out form validation for drop down lists. My website has 10 drop down lists. I want an alert message to be displayed whenever the user selects a blank field from a drop down list. One of the sample drop down list runs as follows:
[Code]...
How can I include a function that displays an alert message whenever a user selects a blank option from the drop down list?
I have a scenario where I have the following jquery Code: $("#frompdc<?php echo $JavaCnt;?>").change(function(){ var id = $('#id<?php echo $JavaCnt;?>').attr('value'); var frompdc = $('#frompdc<?php echo $JavaCnt;?>').attr('value'); var topdc = $('#topdc<?php echo $JavaCnt;?>').attr('value'); $.ajax({ type: "POST", url: "AJ_Update.php", data: "firm=y&id="+ id + "&frompdc=" + frompdc&topdc=" + topdc });
And some php to insert this data Code: mysql_query("UPDATE TBLTRANSFERS SET FROMPDC = ".$_POST['frompdc'].", MOD_TS = '". $timenow ."' WHERE ID = ".$_POST['id']);
I'm trying to throw some validation in here which I can do in php (a language that I'm much more proficient in) but can't figure out how to get the two together. I want to be able to do a select against another table I have for both the frompdc and the topdc. Code: $tofpdcresult = mysql_query("SELECT * FROM tbltransferspdcexclusions where FROMPDC = '".$frompdc."' AND TOPDC = '".$topdc."'"); $tofpdcnum_rows = mysql_num_rows($tofpdcresult); And if it exists I want to give a popup message to the user as well as blank out the field.
I'm struggling with two things: How do I get ajax to run two queries and return the results to a popup window? How do I blank out the field in the form?
There will be a pop up menu upon detection of a blank field and I need to stop further execution of the script. How do I achieve that?
<?php if ($email_to == ' ' )?> <script language="JavaScript" type="text/javascript"> window.alert("Please enter your the to field. Thank you."); </script>
I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right
I am trying to validate a web form. Someone else wrote the Html code and implemented it with an iframe using asp and php. I didn't want to mess too much with the code so I decided to use javascript to make the form validate, before it was sending email alerts with every field blank. For the most part the validation works but it skips the email field for some reasons and is really bugging me to death. this is the code:
This is my form, i would like to default the select box to USA, and default the text field to a name such as 'Sarah' and the hidden field to another number like ??', when the user clicks on the check box, otherwise the fields should be blank, the value of the select box dosnt matter much, only that it defaults to USA, when the user checks it.
Am using Struts framework. I want the cursor to be on the first field (text box/select box) when i run the JSP. I've tried with the following command <body onLoad="document.login.userid.focus"> login is my form name and userid is text box name where I want the cursor to be but it didnt work.
Okay, new to this magical thing called Javascript and LOVING it. Don't know how I avoided it all these years. :thumbsup:
Running into a stupid issue and I am sure it is just something I am missing. I have a hidden field in my page with the default value of HELLO. I am trying to make a change based on the default value, but I obviously am doing something wrong because it won't display my hidden field value. [code]...
My users are requesting that when they goto my search page, that the cursor already be blinking in the keyword field. Currently you have to click in there with your mouse. Is there an easy way to do this with PHP or even HTML?
How to reset an input field to its default value, which is depend on another. There is a way to clear the input field but not resetting to its default value.
Example
I have 2 radio buttons. Depends of the radio button selection some other input fields are required. Those things are already done using the click function. It clears the input field. But I need to reset to its default value.
It shows a default value which dissapears when the user clicks on the password field. However, because the input field type is set to 'password', whatever I set as the default value is masked by *
Is there any way around this to make normal text appear but still have the input box masked when they start to type the password?
I have to add some technique which will solve the following problem. A form is presented to the user in our web application. Say it has
4 text fields, 2 radio buttons (Yes / No) 1 checkbox 1 select list.
Now 2 textfields are pre-populated, one radio button (Yes) is pre-selected, checkbox is not checked, one option from select list is preselected.
Problem: In 90% of the cases, all that the user needs to do is enter values in the 2 empty textfields and click Submit.
However, the user might change the values in the preselected controls, like check the checkbox, change radio selection from Yes to No, select a different option from the select list, change the default values from the prepopulated text fields.
Now in such a case where 'default' values are changed, I need to show a alert or a popup layer to the user when the submit button is clicked.
Showing a popup layer or an alert: The popup layer/alert will be a confirmation popup which will say something like -
"You have changed the default values for:[all the fields which were changed by user]. This requires you to do [some task] once you submit the form.
If you do not wish to change these defaults, click Cancel. To proceed with the changes, click OK and then Submit."
Clicking OK: If user clicks OK, then all is well. User will click Submit to submit the form and do some task which is required when defaults are changed.
Clicking Cancel: If user clicks Cancel then the defaults should be restored. User is now free to click Submit. Code:
I want to do a form validation and it should return a message like "should not be empty" when the user leaves the field blank..
I have html code like this
Now I want to know how can i display alert message to the user saying that the particular label name should not be empty..
For eg.. here I want to display alert as "Did you find this article useful? field should not be empty".... (Assuming this is mandatory)
I have so many fields like this in my form(checkbox, radio buttons, etc...) and i want to display alert with label name...
How can I do this using javascript.. (I know how to do validation in javascript popping up the alert(without label name), But I am not sure how to display alert with label name))))
I'm developing a web page. It includes 2 text boxes. One text box for city and another text box for std code. I wrote the code for auto suggestion to city. Now i want to pre populate the STD code when ever a known city is selected (when city is selected from the recommendations displayed for city field).
how to create a function to validate that the default text hasnt been submitted, Could I somehow put it in with my validateIt function? By using something like document.forms[0].visitor_name.value =="Enter your name"? Or am I way off?
