Using Javascript To Select An Entry In A Drop Down Box
Jul 23, 2005
I have a dropdown box containing about 10 values.
I would like to create a separate href on my page that when clicked will
make the drop down box go to a specific value. I do not want to have to
refresh the page to do this. Is it possible to have that sort of control
over a drop down box.?
iam trying to use 5 drop downs in my form for user to select languages and each select drop down should not allow the user to select the same language again and all my drop downs are populating individually from the DB on the page so if "English" is selected for "dropdown 1" then again "drop down 2" should not allow "English" to be selected.
So, I am attempting to select a random entry from an array, and then make it so that particular entry will not be selected again until every entry has been selected. Basically, I don't want to see any of the same entries, until all of the entries in the array have been selected.
So if this were my array....
keywords = [ "ppc", "games",
[Code]....
since meta was selected a second time before everything had been selected once.
I would like to see something more like
meta, advertise, gaming,ppc, welcome, home, games, advertise, ppc, since this did not select any entry multiple times before every entry had been randomly selected.( the second loop started at the second "advertise" in case you didn't catch the differences.
But as you can see from the code that I have posted above, I do not know how to do this. I have seen examples where the entries that were randomly selected, were actually deleted from the array entirely but this is not what I want to do. I just want every entry to be selected once, and then for the process to be restarted.
I am looking to build as basic as possible, a form that has 3 select dropdowns that have predetermined options. The user will select the first option and based on that option the second will populate and based on that, the third one will give the last option. Now, when the last one is selected, i need a div or a paragraph displaying information to be displayed.So here's the framework.
Option 1 = fruit or vegitables of which fruit is selected is selected by the user Option 2 = Apples, Grapes, and pears of which apples is then selected Option 3 = Red, Green and Yellow of which Green is selected.
Once green is selected, I need a description about the green aple to be displayed.
I have a textbox on one of my forms that is used to accept a time from the user. I need to write this value to a database to trigger an event later on.
What I'd like to know is...
Are there any functions in javascript that can convert different time formats to a known format (24 hour clock)... 5pm -> 17:00 or 5:00 to 05:00, etc. ???
Assuming that I get the input into a 24 hour format, how can I create a full time/date variable with todays date and the users entered time?
Finally, if the entered time is earlier than the current time, how can I create the above date/time combination using tomorrows date?
I am looking for a general purpose javascript snippet that enables me to <div> or <span> HTML to make portions of the form be hidden and then appear. The form contains about 12 sections and some sections can contain subsections. When the user clicks on a checkbox, I want previously hidden text boxes, radio buttons, text, drop down menus, and additional checkboxes to appear. In some cases, clicking on a checkbox in a section can cause additional previously hidden text boxes, radio buttons, text, drop down menus, and additional checkboxes to appear.
Within each section, a list of individual names is displayed with an initial checkbox beside each name being displayed. Clicking the checkbox beside a name is what triggers the hidden info to be displayed. The server side application is written in php and the field names are assigned using brackets as the array is created. As an example the HTML checkbox beside the first name <input type='checkbox' name='sect1custname[1]' value'First Name'> The HTML for the next name woud be exactly the same except the name field would be defined as name='sect1custname[2]'. All of the other input buttons, boxes, menus, and text would use the same naming conventions so that the server side module can correctly process the data.
I am hoping to keep this as generic as possible so that we can add, change, and/or delete entire sections simply by creating the appropriate HTML and surrounding it with the correct <div> or <span>. I understand that there may need to be some javascript wrapped around the checkboxes.
If you know of , or have, or can develop the code, please send particulars to jscott4272 at comcast dot net. If there are any costs associated with the code, just let me know what they are. If you have any questions or need additional information, please email them to me.
I've got some directory list boxes on the site I'm working on. I made them big and fixed rather than drop-down so they're easier to use in this context. But I had to enable the "multiple" attribute to make that work. The site has no provision for multiple selections so it's a tad annoying when the search function selects more than one name in the list.It doesn't really affect the site's operation but it could be confusing to some people. Is there a way to make the listbox show multiple selections without allowing multiple selections? Thanks for any help.
There is a missing part on my program, it is when you input less than or equal to 65 and greater than 100, a prompt will appear and say "Invalid Entry" and ask you to Input again an entry until you enter a valid entry. For example on Prelim Grade, I input 50, a prompt must appear to say "Invalid Entry" and ask me to input again another entry. Another is how will I terminate the program? When I input an invalid or a valid entry, it is continuing to ask me to input again an entry.Here is my code
Tried searching for this, but can only find js events to remove an item completely from a drop down box once it's been selected. Example: On a page with many fields for entering different DNS server addresses, I have a drop down menu next to each field, and the values are "Main DNS", "Alternative DNS", "Third DNS", "Least Favorable". Since there can only be one main DNS server chosen, I'd like to know if it's possible for js to prevent that choice from being used more than once. Say there is a Main DNS selected, but the user changes his/her mind and wants a different one. When he selects a second "Main DNS", the first item will return to the drop-down default choice (most likely blank). As stated before, I'll gladly accept a link describing this (or even the proper term to use for a google search).
The website I'm currently developing has a search area where users can narrow down where or what service they would like to view.The problem I'm having is, I have certain things that fall into only certain areas.Here is the actual form:http://www.xgfx.co.uk/drop-downs.jpgAnd this is the code behind it:
New to Javascripting, new to forum. I searched the forum, and tried to adapt, to no avail. I am building a store and want users to be able to see how two items look together. I have it working, but it uses a drop down. I would like to display many items and have the user click on one "image", from the display of "top" images, to display it on top, and from another section of "bottom" images, click another image to display it on bottom. For instance to see what one plant would look like in different vases. [URL] If I could be picky, is there a way to make it all happen in the BODY of the page? I use DW and a template.
I want to use a <select> drop-down in a form to let my user select a date from a list. The problem is how to easily update the list.
Easiest would be to have a list of dates in a separate file, and have code that would read the dates and write them into the <option> statements of the <select> control. Then when the page with the <select> control opens, the code will open the other file, get the dates, and update the <option>s. And all I have to do is periodically FTP a new date file.
I'm stuck in Visual Basic and FileSystemObject, where I can open a file, read line by line into an array, concatenate a string, and write it into a doc. I can't seem to find similar methods in JavaScript - no duh, because this isn't VB!
So _is_ there a way to do this? Maybe a certain way to create the date file so the code can easily find the values? (Like putting the dates into a table with each <TD> having a unique ID?) And assuming I manage to get the dates, I need to write them into the source HTML, vice in the document body.
What objects, methods, properties do I look at? Are there any samples floating around out there?
[URL]you see the Select Drop Down called: Fonts, well if you choose say Airstrip or Arial the image should change but the problem i am having is. It works in IE9 and FF but doesn't seem to work in IE7, IE8 or Google Chrome i hope someone can help here is the code:
If the dropdown is empty and the checkbox is ticked then whichever car type in the drop down is chosen, it will select that car with the parking option. If checkbox is unticked at any stage it will deselect the parking option with the car type
i hope this is clear. i look forward to receiving some code to try and report back.
I am trying to add a search button next to a select drop down with a HUGE amount of data. The search button opens a popup window that allows you to narrow down choices and select one that is in the drop down(that part works). However I can't seem to pass the parameter selected back to the drop down on the first page to have it as the selected item.
I am working with the scripts in the popup window, and I am trying:
window.opener.document.forms(0).Product(lngBoxNumber).value = x
forms(0) I think that is the first window. Product(1) is the name of the drop down. x is the value I am trying to assign.
I am brand new to Java Script and it makes no since at all to me.Ive looked up Java Script onCHange and really have no idea how to implement what I need.I have a select drop down filled by my database. What I need to happen is when someone makes a selection then the page will gather the information for a separate database and display in in a table.
On a form on one of my pages I have two <select> elements, and each one is paired up with a radio button. The idea is to choose an item from one list or the other and select the radio button of the list you want to use.
I'm using JavaScript to automatically select the radio button corresponding to a list when you click on the list (using the onclick event handler). Is that the best event to change on, or should this behavior be triggered on the onChange event - so if they don't change the value they won't have to re-select the other radio button?
Using the 'onchange' event I can fire a javascript function obscure(). How can I hide the selected number with an Asterisk (like a password)? I've tried several different Googles but I can't find a method that works.
I'm a newbie. I have just working with jQuery for 2 hours. For example I have a drop down list like this:
<select> <option>Fruit</option> <option>Color</option> </select> If I select Fruit, another drop down list appers and give me some selections: <select>
I have a select control that has over 400<option></option>. To cut down on the user having to scroll through all 400 options I have included a text control that acts as a "Quick Index" and with each char entered into the text box the options are narowed. The problem I am having isthe once I have determined which option should be selected, how to set the option to value of "selected"
This code is displaying English and French in the select list.
If we onchange the value in the jsp then its value is reflected properly in the java file.
But my requirement is if you have onchange its coresspoging selected value should be reflected in java file else the default selected value let say English should refelected in the java class.
But unless we cannot change the select dropdown value the the default data is not reflected in java class using bean.
What piece of code i change so that deafult selected drop down value data also reflect in java class also.
