My validate() function is not working quite right since it should validate for at least on checkbox checked and even if opne is checked it will simply display the error message instead of validating. What might be wrong here?
Here's the function (note, all the checkboxes have the id='chk')
function validate(){
var countChecks = 0;
if (document.forms.getElementById == "chk")
{
for (var j in document.forms.getElementById)
if (j.checked)
countChecks++;
}
if (!countChecks)
{
alert('Select some checkboxes!')
return false;
}}
I'm trying to pass data I gathered from a prompt into a later function.
1. Should prompts for information be in their own JS file separate from the HTML page? Or is it better form to have the prompts (for info) in the HTML page itself?
2. I have tried placing the prompts to gather info in several places, each time my script seems to stop after the data is gathered and does not perform the calculations which are contained within a function. The input data is gathered from a prompt, do I still need to "return valuea" and "return valueb" in order to use the input data in the calculation function? Initially I did not feel I did, as I am not performing a calculation initially, just receiving input.
I am by no means a JS programmer, but I like to exhaust all avenues when attacking an issue. A signature fired off on a piece of javascript that came across the wire, with an odd "var unescape" inside of it. I am hoping to throw this code out there, to see if anyone has any insight on what this might be.
I am assuming this is double encoded, but I am not certain. Here is the snippet of code the signature fired off from:
var ibdf=unescape("%u0b0b%u0b0"+"b"); var fdofdopf="xcvb9090";
Does the world need another DHTML popup calendar? Probably not, but I'm writing one anyway. It's unique in that it allows drag selection of a range of dates. Works great on IE6 but I'm having some trouble with Netscape and events. In particular, the mousedown event doesn't work. The event fires, but I can't seem to get a handle on what html element was clicked.
What I'm trying to do here should be simple and I suspect that I'm just overlooking something basic but I'm overlooking it. If you can tell me what I'm not seeing here, I'll be most grateful. This is the associated HTML code. Two statements to be rated from 1 to 10 using radio buttons.
<tr> <td width="25"><strong>A</strong></td> <td width="210">A statement is here</td> <td width="21"><input type="radio" name="SI_QA" id="SI_QA_1" value="1" /></td> (total of 10 lines like this)
EBay has implemented a different way to upload auction pictures --- after browsing for the picture and selecting it, the image preview instantly displays on the screen, which is nice. Apparently this process is being handled locally --- could someone try to re-create this ? ... I imagine its using DHTML or some other technique, I'm not sure how I would code this.
[URL] I'd also like to use this plugin, so I don't have to create complex validation rules. validation plugin [URL]Trouble is, I can't figure out how to prevent form submission without first checking to see if the form is valid. My attempts so far have been based on using submit() to prevent submission of the form if validations valid() method returns false. But this doesn't seem to work. If I use ajaxForm, the submit() function seems to work differently. A form will still be submitted, despite a return false. validate has a valid() method that returns false if the form fails validation. How can I submit the form only if valid doesn't return false?
I'm fairly new to jquery and am using the following code that I know is not quite right but the functionality is exactly what I need except that it won't validate because of how the images below are handled.
I am using the validate plugin on twoseparate sites. It works fine on one site, but on the second, where I am trying to use focus() as well, I keep getting the error message that validate() is not a function. My code is listed below and I am hoping someone can spot the problem where I cannot.
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.
However, I am suck trying to validate the form on the client side with a JavaScript function before the form is submitted.
Here is my index.jps:
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
This post is about the jquery validation plugin. I am using the url() method to validate text fields for valid url input. It works fine, but I want a slight modification where I am checking whether a base directory has been added and not some individual page. For example, not [URL] but [URL]. Any way I can modify that url method to satisfy my needs?
I've built a page which uses javascript to snap roll-over layers to a centered (div) layer. It works fine, and is called when the page loads. However, calling the same function 'onresize' works, but doesn't validate as XHTML - because the XHTML body tag does not support the onresize event handler.
As a consequence, I need to extract the onresize handler into it's own script file and use it to call a page reload.
I can get this to work in IE 6 on a PC, but it doesn't work in FireFox. I really need this to be as cross-compatible as possible. The code I have in the page header is:
Code:
<script type="text/javascript"> function reDo(){ window.location.reload() } window.onresize = reDo; </script>
Does anyone know how to achieve a cross-compatible means of reloading a page upon resizing?
I want to validate(eg: empty validation) my web forms using javascript. How can I use a single javascript function to validate all the text boxes in all the forms. Or else do i have to write seperate functions to validate each web form
I tried taking the quotes off 'errorPlacement' but no luck. In the debugger I see it checking the settings for an errorPlacement function and it's undefined. I ran the function definition through JS Lint and it's happy
I have a simplified version below of a multipart form. There are two steps and two tabs. I want the user to enter their username and email address and click 'Next' which will validate to make sure those fields are filled in, then activate and advance to tab #2 (Step #2) of the form, where they enter their credit card information.
I am having difficulty because username, email and credit card are all in the same form and I need to only validate certain fields on each step of the form. I was thinking I could make a function when the 'Next' button was hit that would validate the first two fields?
Here is what I have so far. I have a 'Next' button which activates and advances the tab to Step #2, but I need to work some form of validation into it before it advances. At the bottom of the page I have a 'Submit' button which is just so you can see that the validation is working if the form is submitted. I just want the 'Next' button to activate a function to only validate the fields on Step #1 (username/email).
I have a gridview in a form that contains a Save ImageButton. I would like to create a Client-side CustomValidator that checks whether the grid is empty or not. If it is empty then I would like to throw an error message to the user. This is my code. In the "Save_btn_Click" event, I check if the page is Valid:
I am Having an account information page which needs to be validated,but the problem is i want each error message to appear under its respective input field. I had tried using errorPlacement but it is showing all error messages at one div id which i had assigned.Is there any way to display error messages under its respective text box(input field) ??? Need of Urgent help.

Here is the url of demo, i already mentioned the jotform upload url with code inside the demo.[URL]
I must be missing something, is there not an easy way to validate inline?
For example, I have a required text input that is given focus on page load, I would like for it to throw an error if the user moves to the next field w/o entering any data.
