  • Bug in Safari: options.length = 0; not working as expected in Safari 4

    - by Stefan
    This is not a real question, but rather an answer to save some others the hassle of tracking this nasty bug down. I wasted hours finding this out. When using options.length = 0; to reset all options of a select element in safari, you can get mixed results depending on wether you have the Web Inspector open or not. If the web inspector is open you use myElement.options.length = 0; and after that query the options.length(), you might get back 1 instead of 0 (expected) but only if the Web Inspector is open (which is often the case when debugging problem like this). Workaround: Close the Web Inspector or call myElement.options.length = 0; twice like so: myElement.options.length = 0; myElement.options.length = 0; Testcase: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Testcase</title> <script type="text/javascript" language="javascript" charset="utf-8"> function test(el){ var el = document.getElementById("sel"); alert("Before calling options.length=" + el.options.length); el.options.length = 0; alert("After calling options.length=" + el.options.length); } </script> </head> <body onLoad="test();"> <p> Make note of the numbers displayed in the Alert Dialog, then open Web inspector, reload this page and compare the numbers. </p> <select id="sel" multiple> <option label="a----------" value="a"></option> <option label="b----------" value="b"></option> <option label="c----------" value="c"></option> </select> </body> </html>

  • I read 3 pages of a JQuery book and here's my reaction and question

    - by George
    My jQuery reaction to the language's flexible "selectors" is probably rooted in this experience: I once had managed a project where a developer constructed a web page that was used by users to provide very flexible search parameters for a search screen using dynamic sql string building based on the user's specified search parameter. The resulting queries were usually very complicated and involved joins to many tables. One of the options that the user had was to choose from one of 3 an options. Depending on the user's choice for this option, the resulting SQL would need to query a different set of database columns. For example, if choice option "A" were selected, the resulting database columns queried would be prefixed with "A_"; if option "B" were selected, he resulting database columns queried would be prefixed with "B_" and so on. The developer choice to write all the complete SQL assuming that the user selected, for example, option "A" and therefore first constructed SQLs of this type: SQL = "SELECT A_COL1, A_COL2, A_COL3 FROM TABLE ..." and then after constructing one of a million possible variations on the Query From Hell, did something like this: If UserOption = "B" then SQL = SQL.Replace("A_","B_") 'replace everywhere End if He insisted that this was the easiest was to code it, and while I understood that, I was concerned about maintenance of this code. You see, this worked for a while, but as the search options grew and the database columns evolved, the various "REPLACE small substring" with another small substring had unexpected consequences when applied to an evolving database and new search options. My feeling is that code should be written as much as possible such that you can add to it without fear of breaking what is already there. I feel a better approach, though a bit more work, would have been to write a function to return the appropriate target column based on a common set name and the user selected option. OK, so what does this have to do with jQuery selectors? Are the ultra flexible JQuery selectors kind of like perform a "replace all" on a SQL string? Handy as hell but potentially creating a maintenance nightmare?

  • Watir question regarding select_list and reloading

    - by AJ
    I have a drop down with multiple options. Whenever you choose an option, the page reloads with data specific with that option. Currently I'm using select.list(:name, strg).set(value) and it does that part just fine, but it does not reload the page with the specific data. Anyone know how to help. When i watch it in action, it doesn't select the option either, but my logs show that it does.Thanks.

  • Change style of text field based on the selection of a combo box using Javascript

    - by baldwingrand
    I would like to change the style of a text field based on the value selected in a combo box. Specifically, what I'd like to do is make the txtDepartment field gray and marked as "read only" if the option value selected in cboSource is 1. I've tried the code below, but I imagine my style code at least is wrong, if not other things. Any help appreciated. Thanks! <select name="cboSource" id="cboSource" onClick="displayDepartment(this);"> <option value = 1>Source 1</option> <option value = 2>Source 2</option> </select> <input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p> <script> function displayDepartment(obj) { var selectedValue = obj.value; var txtDepartment = document.getElementById("txtDepartment"); if (selectedValue == "1") { txtDepartment.style.display = "Disabled style='background-color:#E8E8E8'"; } } </script>

  • Dropdowns don't work on webOS with PhoneGap?

    - by Steve Nay
    I'm trying to use a dropdown in a PhoneGap app I'm writing. It uses a simple <select>: <select> <option value="1">First</option> <option value="2">Second</option> </select> This works fine on Android and the iPhone (including behaving like a native drop-down would on those systems). However, it doesn't appear to work on webOS (neither the Palm Pre itself nor the emulator). The <select> displays properly on the screen, but when I tap on it, nothing happens--I'm not able to make a selection from the dropdown. Why might this be?

  • Chrome Extension - Dynamic Right-Click Menu

    - by user1277607
    I am trying to create an option in the right-click menu that is dynamic based on the user's action. If the user selects some text, then right-clicks, the option will say "Display It". If the user right-clicks without selecting some text, the option will say "Select Some Text First" and be grayed out. I am wondering how do I achieve this? I currently have it so that the option will appear only when the user has selected some text. I am unsure how to modify it to meet my second requirements. chrome.contextMenus.create ({ title:"Display It!", contexts:["selection"], onclick:function(info,tab) { chrome.tabs.sendRequest( tab.id, {callFunction: "displaySidebar", info: info}, function(response) {console.log(response);} ); } });

  • Delay-Load equivalent in unix based systems

    - by saran
    What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

  • Why does this javascript code have an infinite loop?

    - by asdas
    optionElements is a 2d array. Each element has an array of length 2. These are an integer number and an element. I have a select list called linkbox, and i want to add all of the elements to the select list. The order I want them to go in is important, and is determined by the number each element has. It should be smallest to highest. So think of it like this: optionElements is: [ [5, <option>], [3, <option], [4, <option], [1, <option], [2, <option]] and it would add them to link box in order of those numbers. BUT that is not what happens. It is an infinite loop after the first time. I added the x constraint just to stop it from freezing my browser but you can ignore it. var b; var smallest; var samllestIndex; var x = 0; while(optionElements.length > 0 && ++x < 100) { smallestIndex = 0; smallest = optionElements[0][0]; b = 0; while( ++b < optionElements.length) { if(optionElements[b][0] > smallest) { smallestIndex = b; smallest = optionElements[b][0]; } } linkbox.appendChild(optionElements[smallestIndex][1]); optionElements.unshift(optionElements[smallestIndex]); } can someone point out to me where my problem is?

For example, let's suppose I have the question with the id 46, with 4 answers, and 48 users voted for the option #2, 37 users for the option #1 and 39 for the option #4. I want a query that selects that and write these things: 1 37 2 48 3 0 4 39 P.S. VERY IMPORTANT! IT MUST COUNT ONLY NRANSWERS ANSWERS, AND IT MUST ECHO THE ONES THAT WEREN'T VOTED BEFORE.

    - by artmania
    Hi friends, I'm a drupal newbie who needs some advice... I have a news list block at homepage, created with View Module. It is listing all added news' title and link. Everything is cool so far. Now I need to add an ON/OFF option at admin side for homepage news block. When the setting is ON, it will work as it is. When it is OFF, only the titles will be listed with no linking to news detail page. So, now where should I add this ON/OFF option? I have only add/edit/delete pages for each news, there is no common news page to add such option. Should I create an admin page with such ON/OFF option in? Also I think I need to create a db table to keep this ON/OFF status. and controlling this value at homepage block, if it is 1 or 0, and displaying links according to db value :/ it looks too long way Create db table Create an page with ON/OFF option in add php codes to update db for admin's choice get the db value in homepage block to display links, etc. is there any shorter, better way to do what I need?

  • Help with PHP and associative arrays

    - by errata
    Hello. I have to do a simple calculator in php based on user's input and choice from select field, something like this: <?php $a = $_GET['a']; $b = $_GET['b']; $array = array( "option1" => 0.1, "option2" => 0.15, "option3" => 0.3, "option4" => 3, "option5" => 3, "option6" => 16, "option7" => 16, "option8" => 16 ); echo "<form action='calc.php' method='get'>"; echo "<input type='text' name='a' value='".$a."'> of "; echo "<select name='b'>"; foreach ($array as $k => $v) { echo "<option value='".$v."'>".$k."</option>"; } echo "</select> "; echo "<input type='submit' value='='> "; $total_volume = $a * $b; echo $total_volume; echo "</form>"; ?> Well, for now everything works fine, but the idea is that after user submits form, the page reloads with sent amount in input field and selected option which user actually selected... First thing is easy: I just put value="a" in my input field, but I'm not sure how to make a selected option in <select> field??? I started with this: foreach ($array as $k => $v) { echo "<option value='".$v."'"; if ($b == $v) { echo " selected "; } echo ">".$k."</option>"; } ...but this is obviously not working as expected... Please help me with this easy one :) Thanks!

  • Z-index vs Accessibility

    - by MetalAdam
    Here's a simplification of my code that I'm having problems with, in regards to layering. <ul id="main_menu"> <li>Option 1 <ul id="submenu1"> <li>link</li> <li>link</li> <li>link</li> </ul> </li> <li>Option 2 <ul id="submenu2"> <li>link</li> <li>link</li> <li>link</li> </ul> </li> </ul> My issue is that submenu2 seems to be above Option 1. I have tried to give them appropriate z-indexes, but they don't seem to work... I'm assuming because submenu2 is a child of Option 2, and has no relevance to Option 1. Any idea of any work around that would help resolve my issue? I'm using large graphics for most of these links, so the overlapping is quite obvious.
