I have created a registration script in PHP and want a JS feature embedded to tell the user that the 2 passwords they have typed "haven't" matched. If they are identical, then I want the registration to go through as normal, but if there is an incorrect match, then it should stop the script and open up an alert box stating the error. When the user clicks on the "okay" button in the alert box, the script should not try to carry on with the process.
I have seen this feature on a number of registration websites, but I have searched Hot Scripts and some other resources to no avail...
This is my function function func_name(){ if (field1.value == '' && field2.value == '' && field3.value == '' && field4.value == '') { alert("All fields are empty."); } else { if (field1.value != '') { if (field2.value != '') { if (field3.value != '') { if (field4.value != '') { alert("All fields are not empty."); } else { alert("Field4 empty."); } } else { alert("Field3 empty."); }} else { alert("Field2 empty."); }} else { alert("Field1 empty."); }}} If I set all fields to be empty, the alert display "Field1 empty.".
I have this web form that I want to validate only four of the fields (these are just input text fields, one of which is for e-mail). The code is supposed to bring up an alert box when a fields is empty and after the user clicks ok puts the focus on the offending input field. For the e-mail box, it is supposed to also check for correct e-mail address form.
While testing the first field, the alert text box appears, I click ok but the page sends the incomplete form to my processing page and causes and error. Firebug says that "field1 is not defined". Honestly it looks like it is defined to me. Can any of you take a look at the code below and see what I am doing wrong? Only my JS code appears below. I've searched online for possible solutions, but the things I've tried produced similar undefined errors. I admit I need more practice in JavaScript (familiar with JS, not proficient)
In a FrontPage web I'm trying to validate an email address to be sure it meets some minimum format, perhaps something like ?@?.* I was told that this could be done in javascript. Any help would be very much appreciated.
Unfortunately, sometimes the target webpage is not available and I get "page not found". That immediately kills my application, until I manually restart it.
Is there a way in javascript to first check if a link exists before the form is submitted?
For php programmers, an example of what I want will be:
if(fopen("http://www.example.com/", "r") { do something here... }
I have created two pages, the first page is stored in a free public web server, and the second one is stored in a personal computer. This computer is not allways on, so, sometimes, the page could not load.
I want to create a "Zero" page that checks if the second page is accesible (and if it is, then redirect). And if the page is not accesible then redirect to the public server.
I'm working on a script that needs to check if a window is open. The window is opened from a different function then the one that has to do the verification. Will this work? What is the best way to do this? Code:
I have a form with a javascript form validator to check against all fields to make sure they are entered in correctly and to reduce spam. I am using Code:
var allowedChars = /^[a-zs]+$/i;
to specify that I only want characters and so on. Is there a way to reverse that to say this html input field CAN NOT contain any of the following? I want to check against a comment box to make sure no url address is entered (http:www.) because most spam contains urls in this field. Is there a simple solution?
What is the standard practice to verify that a page has loaded succesfully in a frame when one issues a framename.href="url"? For example, detecting 404's, or other errors (like domain doesn't exist).
I use the following to verify that a user has entered a number between 0 and 99 in a form:
It seems to work fine in all browser / machine combos except Firefox on a Mac, when entering 0 returns false (I don't know if entering other numbers also returns false.)
I want to verify that the data in my form in HTML is already exist in my database if this is true then the form must not be sent. I know this is done in javascript but I can not found the right solution. I would like an illustrative example.
I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).
The following Javascript will return an error message if the user did not enter any value into the zip code field. The form will submit even if user entered only 1 character. Does anyone know how to change this to at least minimum 5 characters must be entered into the field?
...} var fname = "CustomFields_17_2"; var fld = document.getElementById(fname);
Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it.
function Clear() { var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); [code].....
Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button?
Heres my javascript code that will verify email from email input field and check if the checkbox (I agree condition) was checked:
[Code]....
However, this will work fine when calling with a link "javascript:validate('inputForm');" but if I try to prevent users by submitting form with pressing enter I put it in form onSubmit parameter: <form .. onSubmit="javascript:validate('inputForm');"> which will check the forms and submit data (do return) no matter if it matched or no.
