I am currently designing an HTML page with a form with a post method.
The page is calling itself so with the details that are passed will
vary how the page will look i.e. number of results from the sql query
that is being run. I'm trying to catch these using a javascript
function which is:
var qsParm = new Array();
function qs() {
var query = window.location.search.substring(1);
document.writeln(query);
var parms = query.split('&');
for (var i=0; i<parms.length; i++) {
var pos = parms[i].indexOf('=');
if (pos > 0) {
var key = parms[i].substring(0,pos);
var val = parms[i].substring(pos+1);
qsParm[key] = val;
}
}
}
and then just calling the array to get the value, in this case
qsParm['num_res']. The above function doesnt work for post but does for
get. I'm fairly new to javascript and am assuming this line is at
fault:
After a javascript-generated post event (this is a post, not ajax messaging) the current screen has to be redrawn. But on *long forms* (longer than a single screen) then the current screen positioning is lost, and the current form ends up redrawn, with a different vertical positioning--after the post event.
However, If I sent the x,y mouse position as post parameters, and if the current widget (that generated the post) had a well-known anchor tag name, would there be a way to combine that much information, after the post, in order to redraw the form close to it's original vertical positioning?
There are different ways by which values of variables can be passed between forms. One of the ways is to use the setTimeout to pass the values or data. Here the biggest advantage is we can pass data to a different site even running automatically.I would need from someone a bit of help to pass the variable links from form1 to variable strLink in form2 using SetTimeout.We have the following schema:An options select menu where value of the option, sent with a submitted form, is specified with the value attribute. In the absence of a VALUE attribute, the value is the content of the option element.
I'm struggling with a script for an e-commerce site.When the user clicks the add to cart button they are currently taken to a PHP shopping cart page, but the client wants them to stay on the same page after they press the button and get notified that an item has been added to the cart.The add to cart button is a form submit button, because there is also a quantity field for each item. I would have cracked this by now but there are multiple add to cart buttons on each page and when I submit the form only the data from the first form in the page is sent to the cart page.Here's a dummy version the JavaScript:
Code:
$(document).ready(function(){ $('.subbtn').click(function(){ $('<p id="add">Added To Cart</p>').insertAfter(this).fadeOut(3000);[code].....
At the moment I've got it set so that AJAX returns information to the page (just so I know it works), but this won't happen on the actual page.So, as far as I can tell, I need a way of POSTING $(this).parent(); $('[name=quantity]').val(), but I can't seem to find the correct syntax.
I am trying to create an HTML form in which user will enter different items (he wants to purchase) in text fields. One text field is used for one item. Now it is not known in advance how much items the user will purchase so we cannot decide the total text fields required in advance. Is is possible to increase the number of text fields (using JavaScript) one by one if the user requires more fields
I'm having some trouble naming variables in javascript. Actually, my html has multiple form names (form, form1, form2, etc..., and im just having trouble understanding how to access elements within.For example: I get error:Message: 'document.forms.form.bname' is null or not an objectWhen I use the following code:
var bname = document.forms["form"].bname.value; And when I try this: var bname = document.form.bname.value;
I am a newbie trying to generate an alert message when a user leaves a username filed blank in an html form using an external javascript. Following is the code for html file.
[Code]....
However, if I swap the positions of the username and first name i.e. place the first name before the username, I do get an alert message if the first name is left empty. I do not wish to hijack an existing thread. Please let me know if there is an existing thread on this issue..(I could not find one).
This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.
Here is the script: Code: function flip(pizzatype) { if (pizzatype.value == "Veggie Special") { document.forms["pizzaform"].topping.value = "veggies"; } else if (pizzatype.value == "Meat Special") { document.forms["pizzaform"].topping.value = "meat"; } else if (pizzatype.value == "Hawaiian") { document.forms["pizzaform"].topping.value = "hampineapple"; }}
The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement. if(pizzatype.value == "veggiespecial")... Shouldn't it be just (pizzatype == "veggiespecial")? Why does it have to be pizzatype.value? Where the heck does the .value come from???
I have come in need of assistance in guiding me in the right direction. My intentions are to create a web-based page where one can select from a few drop down menu's, and enter a few select pieces of information. This information would then be logged for later purposes, when the user chooses to retrieve this information (during the initial usage, no long term storage) in the format of a report.
I have a web page with two forms, when I click the button on one of the forms, the onclick event goes to a javascript that emails the first form and then the second form. This is correct, this is the way I want this to work. It's simple, it's easy, it works!
However, it only works in FireFox and Internet Explorer, it will not work in Google Chrome browser.
I've spent many hours trying lots of various ways to implement this so I'm not interested in speculating about possible solutions that might work, I've already tried too many of those.
Also, it needs to work this way, not combining the forms, etc.
Does anyone have any tried and tested solutions that work with Chrome? code...
I know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client.For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead.
What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once?Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it.I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying.
function validate_form(){ if(regform.reguser.value == ""){ alert("Please completed the selected box");[code]....
to validate a simple registration form, however I initially tried to streamline this function by cycling through an array using a loop to point to various input elements in the HTML page itself. I found that when trying to use a variable in the aforementioned if statements the javascript failed to work i.e.
var test = "reguser"; if(regform.test.value = ""){ }
I know the javascript is looking for the input element "test" instead of "reguser" but is there any way I can force it to look for the contents of the variable.
I am trying to create dynamic content using append and appendTo functions. It seems to work fine and I can see the new elements on the fly using a Button to execute a customized function based on this jquery methods. something like this:
Very new to JavaScript so I'm sorry if this is a daft question, I have searched for answers first and could not find anything that works for me ... so .. One html form with two submit buttons. On submit (save changes) posts back to the same page and updates a database. The other submit button (preview) should open a op-up showing what the data would look like if the user should press save.
I want to make few forms but 1 submit button. I want to do 1 page , 5 forms , 1 submit button so when i click on the submit button it will send the 5 forms as 1 form.
I need to capture input from a form in the run time and send those values as URL parameters using HTML POST.
I am using:
Here searchText and searchFilter are the input values. When I run the app, I don't see the values but I see "frm.searchText.value" and "frm.searchFilter.value" getting passed as parameters.
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.
