Ajax And Php - Automatically Population A Html Selection Option Based On The Choice Of The Previous
Jan 22, 2010
Not sure if this should have went into the php or javascript forum. I am trying to setup a script that will automatically population a html selection option based on the choice of the previous selection. If hard code everything it will work fine example manufacturer is currently being populated dynamically when the pages loads. The issue is I am can't pass pass the manufacturer variable through to be processed to only retrieve the models for that manufacturer. The code also uses a standard ajax script which httprequest in it.
I have spent the last 6 hours working on this, and I am about to lose my sanity. I need your help very desparately. I want to create some radio buttons for building a computer for a class project. Basically, what I have now is the radio buttons in separate groups, and a function that calculates the total price of the items selected. But what I am finding impossible to get is this: I need to set it up such as that if you select a radio button in one group, it disables part of the second. What this means in my work, is that say I choose AM3 as the CPU socket, only AM3 motherboards and processors will be enabled, and the rest in these categories will be disabled.
I am trying to set it up in a way that when you first open the page, cpu, motherboard and ram groups all disabled, then based on your socket choice you get different options for motherboards and processors, and then based on your motherboard choice you get different choices for RAM.
I have 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?
What I would like to do is have a page with a dropdown menu, and depending on which option the user chooses from the dropdown, reload the page and display a particular iframe below the dropdown, based on the users choice. Also, a default iframe would load (the one connected to the default choice in the select box). I was trying to make this work with PHP (without having the user having to click a submit button) but I couldn't find a way to make it happen.
I'm populating a select pulldown based on the value of a previous option on a pulldown
When I run it on the firebug command line it works fine, but when it is run in the source it does not populate the html with option's for the pulldown.
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made. Here is the code I have so far.
I want to have several forms on one page that are not displayed until a selection is made from the category drop down box(select element). The form displayed will depend on the selection made.
i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long
I have a page which has a dropdown box.On selection a value is sent to a php script (Ajax), based on the value a html table is created and sent back to the responseText.The table is outputted to the html page, I want the table to have sortable columns, so I have used jquery datatables for this, but it is not working.I have cut and pasted the exact table into the html and ran the page, and then sorting works.
I want to know how I could direct the user to a html document based upon which option I have chosen in the list (see above). So for example...
If I have chosen '1' in the list (see above), then when I submit the form, I will be directed to a page detailing information related to option '1'. If I have chosen '2' in the list (see above), then when I submit the form, I will be directed to a page detailing information related to option '2' etc.
I have not been able to get this output change when the drop down menu choice changes. I have looked at numerous examples but I can't find one that has this simple output change. What am I missing?
The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.
Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.
I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)
I have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice.
This is my criteria:
If someone chooses checkbox number 1, they cannot choose any other checkbox.
If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below.
If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below.
One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed.
I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work.
I am facing an issue where a link on my website opens in a new window if you simply click on it. However, if you right click and say open in new window or new tab, it opens the same window (URL) again from where the link is clicked.
Self Service Option is a link and the JSP calls a function getSelfServSite() when the link is clicked. This is how the code flows in my case
function getSelfServSite() { getToTheLink("${myConfigInfo.selfServiceURL}"); // this is because the URL is configurable
[Code].....
I want it to go to the right link no matter how the user click it.
I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load.
Ok so I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load.
Is there any way to enable a form element(s) based on the selection in a <select> drop-down? I'm trying to enable/disable a group of checkboxes depending on which option is chosen in the <select> above it.I know how to enable/disable something when a box is checked (or text is entered into it) but I have no clue how to handle the <select> option.
I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.
I have a form with input boxes in it. The type that tells you what to put in the box is automatically written in the box, so you have to erase it to type in your entry... How do I make it so that when you click in the input field, it automatically erases the type so you don't have to manually erase it before entering your information?
This code block occurs several times. Sometime the first div ist just "inner" and the second div is missing.
Now I need to update the "new" DIV based on the height of the previous inner-new DIV. For one it works fine:
var height = $('#inner-new').outerHeight(); $('#new').css('margin-top', height*(-1)-30);
But how could I re-use this universally for all my boxes. It needs to check if the DIV "box" contains the DIV "inner-new" as first element, if that is true it need to update the DIV "new".
I tried several things with $('#box').each(function(i) { ... }); but couldn't come up with a solution.
I was wondering if it's possible to make it so that once a user selects a certain option in a list, it makes the next input for that form change to either a textfield or a list without losing the values entered in the inputs above.I know PHP is a server-side script, does that make this not possible?
I need to put previous/next navigation button images on a lot of slides.If i am on slide 3 I'd like javascript to identify previous button as slide2.html and next button as slide4.html and so on
I don't know what it is I am doing wrong, I am trying to get the menus to either expand or contract based on their previous states, i.e if already expanded if clicked again contract, and if contracted, expand, so far it doesn't work for the about and services link(but works for the expand all and contract all links), Code:
I am creating a form in which a checkbox is checked based on the info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients.So any idea on how I can accomplish this using Javascript?
