  • How to make the value of one select box drive the options of a second select box

    - by Ben McCormack
    I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this dynamically on the client (using javascript or jQuery) rather than having to submit data to the server. For example, let's say I have the following Menu Categories and Menu Items: Sandwiches Turkey Ham Bacon Sides Mac 'n Cheese Mashed Potatoes Drinks Coca Cola Sprite Sweetwater 420 I would have two select boxes, named Menu Category and Items, respectively. When the user selects Sandwiches in the Menu Category box, the options in the Items box will only show Sandwich options. I'm stuck as how I might approach this. Once I filter out the 2nd list one time, how do I "find" the list options once I change my menu category in the 1st list? Also, if I'm thinking in SQL, I would have a key in the 1st box that would be used to link to the data in the 2nd box. However, I can't see where I have room for a "key" element in the 2nd box. How could this problem be solved with a combination of jQuery or plain javascript?

  • jQuery - select onchange to slide in / slide out div or form

    - by slayaz
    Hi, I am trying to enhance a form, by showing only relevant fields depending on initial selection via a form select field. It is an order form for 3 products and all 3 products have unique properties. My idea was to hide all the content in divs, then reveal the relevant div when the product is selected. I have found some solutions that show / hide a div, but none with any animation. It doesn't have to be a slide but just something nice! The alternative is instead of revealing a div, would be to load a seperate form, but this seems unnecessary. I am not sure whether i need a plug in, as I am pretty new to jquery. What i have in the html is: <style type="text/css"> .hide { display:none; } <select> <option value="" >Please select product below</option> <option value="pro1">Product 1</option> <option value="pro2">Product 2</option> </select> <div id="pro1" class="hide" >Product 1</div> <div id="pro2" class="hide" >Product 2</div> Many thanks in advance

    - by Patrick

  • Need an alternative to two left joins.

    - by Scarface
    Hey guys quick question, I always use left join, but when I left join twice I always get funny results, usually duplicates. I am currently working on a query that Left Joins twice to retrieve the necessary information needed but I was wondering if it were possible to build another select statement in so then I do not need two left joins or two queries or if there were a better way. For example, if I could select the topic.creator in table.topic first AS something, then I could select that variable in users and left join table.scrusersonline. Thanks in advance for any advice. SELECT * FROM scrusersonline LEFT JOIN users ON users.id = scrusersonline.id LEFT JOIN topic ON users.username = topic.creator WHERE scrusersonline.topic_id = '$topic_id' The whole point of this query is to check if the topic.creator is online by retrieving his name from table.topic and matching his id in table.users, then checking if he is in table.scrusersonline. It produces duplicate entries unfortunately and is thus inaccurate in my mind.

  • Adding select menu default value via JS?

    - by purpler
    Hi, i'm developing a meta search engine website, Soogle and i've used JS to populate select menu.. Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it.. Is there a possibility to preselect one value from the menu via JS after the page loads? This is the code: Javascript: // SEARCH FORM INIT function addOptions(){ var sel=document.searchForm.whichEngine;for(var i=0;i<arr.length;i++){ sel.options[i]=new Option(arr[i][0],i)}} function startSearch(){ searchString=document.searchForm.searchText.value;if(searchString!=""){ var searchEngine=document.searchForm.whichEngine.selectedIndex; var finalSearchString=arr[searchEngine][1]+searchString;location.href=finalSearchString}return false} function checkKey(e){ var character=(e.which)?e.which:event.keyCode;if(character=='13'){ return startSearch()}} // SEARCH ENGINES INIT var arr = new Array(); arr[arr.length] = new Array("Web", "http://www.google.com/search?q="); arr[arr.length] = new Array("Images", "http://images.google.com/images?q="); arr[arr.length] = new Array("Knoweledge","http://en.wikipedia.org/wiki/Special:Search?search="); arr[arr.length] = new Array("Videos","http://www.youtube.com/results?search_query="); arr[arr.length] = new Array("Movies", "http://www.imdb.com/find?q="); arr[arr.length] = new Array("Torrents", "http://thepiratebay.org/search/"); HTML: <body onload="addOptions();document.forms.searchForm.searchText.focus()"> <div id="wrapper"> <div id="logo"></div> <form name="searchForm" method="POST" action="javascript:void(0)"> <input name="searchText" type="text" onkeypress="checkKey(event);"/> <span id="color"></span> <select tabindex="1" name="whichEngine" selected="Web"></select> <br /> <input tabindex="2" type="button" onClick="return startSearch()" value="Search"/> </form> </div> </body>

  • if else on javascript with the value of a select box (pure javascript)

    - by user983248
    I'm working on a select box that have images instead of text, (on the background with css). <script type="text/javascript"> function onChange(element) { element.style.backgroundColor = "Yellow"; element.className = "on_change"; } </script> <select onchange="onChange(this);"> <option value="1" style="background: url(/one.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="2" style="background: url(/two.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="3" style="background: url(/three.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> </select> The problem is how do I get the value of the selected option and if is 1 set one image and if it is two set another image as the background using pure javascript (no jQuery)? I know that selectedIndex is the key to my problem, but I'm clueless of how to use it or how to use it on an if else statement. The script above is just one of my trials, I actually use the script above to perform the same task. <select onchange="this.style.backgroundColor=this.options[this.selectedIndex].style.backgroundColor; this.style.color=this.options[this.selectedIndex].style.color">

  • What does ER_WARN_FIELD_RESOLVED mean?

    - by VolkerK
    When SHOW WARNINGS after a EXPLAIN EXTENDED shows a Note 1276 Field or reference 'test.foo.bar' of SELECT #2 was resolved in SELECT #1 what exactly does that mean and what impact does it have? In my case it prevents mysql from using what seems to be a perfectly good index. But it's not about fixing that specific query (as it is an irrelevant test). I found http://dev.mysql.com/doc/refman/5.0/en/error-messages-server.html butError: 1276 SQLSTATE: HY000 (ER_WARN_FIELD_RESOLVED) Message: Field or reference '%s%s%s%s%s' of SELECT #%d was resolved in SELECT #%d isn't much of an explaination.

  • Wordpress Database SQL query help needed

    - by i-CONICA
    Hi, I've written a PHP script to access the latest item from the wordpress database, which it does. But I need to use it twice, once for the latest item from a specific category, and another from a differerent category... But right now I cannot figure out how to put the query together. The post has a post_parent, which in another table, called wp_term_relationships, is referred to as object_id, and has a term_taxonomy_id, which then relates to a different table, called wp_terms where the term_taxonomy_id is now term_id and then you have the category slug name available to select... I really cannot understand how this query would work though. I've made a really crap mock up of it, to try to "visually" explain what i'm trying to do... SELECT * FROM wp_posts WHERE post_status = 'publish' AND (SELECT term_taxonomy_id FROM wp_term_relationships WHERE object_id = post_parent) AND (SELECT slug FROM wp_terms WHERE term_id = term_taxonomy_id) ORDER BY ID DESC LIMIT 1 Really would appreciate some help... Thanks.

  • How to join nearly identical several queries into one?

    - by Devyn
    Hi, Assume I have an order_dummy table where order_dummy_id, order_id, user_id, book_id, author_id are stored. You may complain the logic of my table but I somehow need to do it that way. I want to execute following queries. SELECT * FROM order_dummy WHERE order_id = 1 AND user_id = 1 AND book_id = 1 ORDER BY `order_dummy_id` DESC LIMIT 1 SELECT * FROM order_dummy WHERE order_id = 1 AND user_id = 1 AND book_id = 2 ORDER BY `order_dummy_id` DESC LIMIT 1 SELECT * FROM order_dummy WHERE order_id = 1 AND user_id = 1 AND book_id = 3 ORDER BY `order_dummy_id` DESC LIMIT 1 Please keep in mind that several numbers of same book is included in one order. Therefore, I list order_dummy_id by descending and limit 1 so only LATEST ORDER of A BOOK is shown. But my goal is to show other books in that way in one table. I used group by like this ... SELECT * FROM order_dummy WHERE order_id = 1 AND user_id = 1 GROUP BY book_id but it only shows order_dummy_id with ascending result. I have no idea anymore. Looking forward your kindness help!

  • Are Conditional subquery

    - by Tobias Schulte
    I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out?
