JavaScript - Validate Function Won't Accept A Space
I cannot get an address entered on a form to validate unless I leave out the space between the number and the street name. The second line of the function shows the characters that it will accept. Every way I tried to add a space to that list doesn't work.
function isAlphanumeric(elem, helperMsg){ var alphaExp = /^[0-9a-zA-Z]+$/; if(elem.value.match(alphaExp)){ return true; }else{ alert(helperMsg); elem.focus(); return false; } } (This is from a tutorial I'm studying to learn how to do validation. It seems strange that the folks who put this thing together don't know there's a space between the house number and the street name. Or does that only apply to my street?) Any ideas, J Similar Tutorialshiiii, im new to javascripts . Can anyone help me to know that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry.... plz share knowledge u will be more knowledgeable Hello all, I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine, thankfully. However, I am stupidly suck trying to validate the form on the client side with a JavaScript function before the form is submitted. Here is my index.jps: Code: <%--

Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given. Am I correct in calling the function onClick? The validation essentially needs to be so that: - Student field contains a string - Score1, Score2, Score3 and Score 4 contain a number between 0 and 100 Any help is most appreciated, Cheers, Beetle. I'm probably missing something simple here. I have this function called display: function display(name3,office3,officePH3,mobile3,email3) { document.getElementById('viewer').src=('Location_Files/')+(office3)+('.htm') } It's supposed to take 5 values and do various things with them. When I only had one parameter it worked fine, it took an office number which was the value of a listbox option and turned it into a path and then pointed an iframe to that path. Then I changed it so the value of the listbox option was 5 parameters separated by commas. Here's the listbox now: <select onchange="display(this.value)" multiple="multiple" id="People" name="People" style="border-style: none; height:260px; width:220px;"> <option value="test name,1656,phone,NONE,email">Loading</option> </select> You can see display is executed as "display(this.value)" so in theory it should take "test name,1656,phone,NONE,email" as its parameters and it should accept 1656 as the "office3" parameter. For some reason it's not working out that way, the function executes and the iframe changes but I get an unable to display webpage message like the path is broken. Can anyone see what I'm doing wrong? figured out, sorry
Hi All, Im currently working on a bidding application built within ASP.Net and i have found this javascript snippet to only allow numeric values in the desired <asp:textbox> which is working fine, but i want to allow the user to add a decimal place. For example, say the bid is 1.50 they should be allowed to enter 1.51 but as i cant imput (.) i end up putting in 151 heres the snippet it may be a slight modification but im new to javascript so any help of knowledge will be highly appreciated Code: function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
}
thanks in advance Hey everyone, I am attempting to use some code from the website Dynamic Drive and the page can be found here. http://www.dynamicdrive.com/dynamici...acceptterm.htm Basically it is javascript code that requires people to check a box before being able to submit a forum. I implemented the code into my site just fine. However I want to be able to use a image submit button rather than a submit button. Since I am not proficient with Javascript I have no idea where to go from here or how to change it to work with an image/paypal button. Here is the code I have so far. Script at top of the page Code: <script>
//"Accept terms" form submission- By Dynamic Drive
//For full source code and more DHTML scripts, visit http://www.dynamicdrive.com
//This credit MUST stay intact for use
var checkobj
function agreesubmit(el){
checkobj=el
if (document.all||document.getElementById){
for (i=0;i<checkobj.form.length;i++){ //hunt down submit button
var tempobj=checkobj.form.elements[i]
if(tempobj.type.toLowerCase()=="submit")
tempobj.disabled=!checkobj.checked
}
}
}
function defaultagree(el){
if (!document.all&&!document.getElementById){
if (window.checkobj&&checkobj.checked)
return true
else{
alert("Please read/accept terms to submit form")
return false
}
}
}
</script>
Form Code: <form name="agreeform" onSubmit="return defaultagree(this)" action="https://urlhere.com" method="post"> <input name="agreecheck" type="checkbox" onClick="agreesubmit(this)"><b>I agree to the above terms</b><br> <input type="Submit" value="Submit!" disabled> <!--<input type="image" src="https://www.webpage.com" border="0" name="I2" alt="PayPal - The safer, easier way to pay online!">--> </form> <script> //change two names below to your form's names document.forms.agreeform.agreecheck.checked=false </script> Please note that the paypal button is commented out in this code as it doesn't work right now and the submit button works. I think the following code needs to be changed to a different check to check for a specific paypal button but I am not sure how to do it. Keep in mind I have four different paypal buttons on the same page so picking just this one is important. Code: if(tempobj.type.toLowerCase()=="submit") Any help with this would be greatly appreciated! Regards, Frank I have a group of checkboxes named "list[]". I want to validate that at least one is checked. How can I do this?
Please see my Booking Form here http://www.n-v-m.co.uk/Booking.html The form is very nearly finished but I have no experience with JavaScript at all so I am hoping somebody can tell me how to do the finishing touches. All I require is: 1- On clicking the 'Submit order' button I would like the browser to check to see if the 'Is Vehicle roadworthy with full M.O.T.:' List/Menu is set to 'Yes' and if not it needs to return an alert stating it must be set to 'Yes' to proceed... Somebody kindly helped show me how to do the alert before so this is working, but, the problem at the moment is after clicking 'OK' to close the alert, the form is still submitted. At this point instead of the form being submitted I would just like the browser to return to the form. 2- There is a checkbox on the bottom of the form that states 'I agree with the Terms and Conditions'... To be able to proceed with a booking I need the customer to check the box... On clicking 'Submit order' if the box isn't checked I would like an alert to appear and the form not to be submitted. 3. When both the above criteria have been met and the form is ready to submit... I would like the browser to re-direct to http://www.n-v-m.co.uk/Thankyou.html which is a page I have already created on my server. Thanks for taking your time to read this... If it helps I have posted both my HTML and PHP codes below: Booking.html Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

hi, I would to validate a textbox, and limit it to 3alphabets and 3 numbers. That is after the user have input 3 alphabets, he can only enter 3 numbers and nothing more. Can someone help me out? How do I fix the problem that autocomplete does not validate, I have heard before that there is a dirty way to do this but did not want to do this before, but now feel i must as my boss wants the site error free ! does anyone know how I do this ? All, I have a page that has some checkboxes in it. I have the following function for that: Code: function checkbeforesubmit(field)
{
for (var i = 0; i < field.length; i++){
if(field[i].checked){ // if a field is checked form is submitted
alert("You have checkboxes that are selected. Add the photos before you go to the next set of pictures!");
return false;
}
}
return true; // if no fields are checked form not submitted
}
I then a link to go to the next page and I want to check to see if any checkboxes are selected before I go to the next page. I try and check this by doing this: Code: onClick="checkbeforesubmit(document.photos.elements['picbigid[]'])" It does the check and says that a checkbox is selected but will still go to the next page anyway. How can I stop it from going to the next page? Thanks! I am trying to create an onChange action that will validate that confirmation checkbox has been checked, and if not, popup an alert message and put the focus on the checkbox input and change the class of the container DIV to "highlight". Here is the form, with the 'onchange' trigger: Code: <form id="checkout" name="my_form" method="post" action="!---SCRIPT_NAME---" onsubmit="return validForm(this);"> <div id="verification" class="aligncenter required"> <input type="checkbox" id="verified" name="verified" value="" /> <label for="verified">YES</label>, the items and quantities shown above are correct.</div> <div class="required"><label for="name">Name:</label><input id="name" name="contactname" type="text" class="L" onchange="" /></div> <div class="required"><label for="company">Company Name:</label><input id="company" name="company" type="text" class="L" /></div> <div class="buttonRow"><input type="submit" name="VERIFY" class="btn red" value="Continue" /></div> </form> And here is my javascript code: Code: function verifyOrder() {
if (document.my_form.verified.checked != "true") {
alert("Please verify the contents of your order");
document.my_form.verified.focus();
getElementById('document.my_form.verification').className='highlight'
return false;
}
}
But this is not working and generates errors in firebug. What am I doing wrong? Thanks!! Is there a y regular expression which we can use in JavaScript to validate URL? Or any other type of validation to validate URL which has http or https?
I am trying to make validation for a form but the bit I am stuck on now is: Code: <input class="submit" type="submit" value="Submit" id="submit" name="submit" onclick="return validate();" /> Do I have to add 'verify' instead of the 'validate' I mean is this a set thing in JS as I want it to go to the JavaScript code which is validate.js I should add that the form is XHTML and there is also a captcha with it. So I would not know how to add the onsubmit to the beginning of the form. I need help please. I'm trying to validate when a user selects an item from the equipment select list they must select a reason code as to why they are ordering the item. This must work across all rows. Also the field to the left of the equipment select list should allow the user to key in the item # of the part and the select list automatically gets selected with the part. How the heck do I do this. I tried the functions I have included but they suck! Please help me Tracy Code: <script>
function validateReason(){
var tr, i=1;
while(tr=document.getElementById('Child'+(i++))){
var txtV=tr.getElementsByTagName('input')[0].value
var selS=tr.getElementsByTagName('select')[0].selectedIndex;
if(txtV.length>0&&selS==0){alert('If you enter a quantity you must select a reason!');return false}
}
}
function change_uids(uid){
var uids = document.getElementById("uids");

uids.options[i].selected = true;

Hello guys, this is my first post here, im a newbie in javascript and i need to limit a textbox to only be 1 or 0, I dont want to use a checkbox because i would like the users to really be typing. heres what i got: Code: <input name="test" type="text" onchange="validaten(this.value)" size="15" />
<script type="text/javascript">
function validaten(test)
{
if (test != 0);
alert("Only 1 and 0 are allowed");
}
</script>
Can you please help me? Arrrgggghhhhhhhhh - help.... - LOL Now I've got that over with, hope someone can help. Am just learning regular expressions and am trying to validate UK format telephone numbers (have had an extensive look on the web and only examples I can find are US tests). Anyway, I want to learn to do it myself. UK phone number rules a Must start with a 0 in position 1 Next 2 to 4 characters must be a number Next character can be a space or a dash Next 6 to 9 characters can be a number, space or dash only Anyway, as I say, am new to regular expressions and trying to learn so I tried to write the expression to fit the rules above - see below: Code: ^[0]{1}\d{2,4}\s|-{1}\d|\s|-{6,9}$
My logic (for what it's worth - LOL) tells me this should work, but it doesn't - it accepts letters as well - which I really don't understand yet. Anyway - hope someone can help. Thanks Dominic |
