  • jQuery slideDown() not animating (jquery-rails 3.0.4; jquery-ui-rails (4.0.5)

    - by Michael Guren
    I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file: if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); } This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect. I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up. This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me. Thanks.

  • Having onFocus do several things.

    - by Jakob
    So I have this input tag <input ... onFocus=...> and what I want is for a warning popup to come up if somebody clicks to write in the input field. After the person has read the warning he/she closes the popup and can continue to write in the field. I have managed to implement the popup just fine but my problem is that I lose focus on the input field when the popup comes up so the next time I click the field the popup comes back again and im back on square one. The system I work on uses php and javascript so and I cannot use anything other than that to solve the problem and my experience with both php and javascript is limited.

  • how to make a border area go around the content of a page where there is a footer fixed to the bottom of the page and an header fixed to the top

    - by user277498
    consider the following: http://jsfiddle.net/PxabT/10/ There are 3 divs hd, bd, ft. hd is fixed to the top. ft is fixed to the bottom. I want the lime colored border to go totally around the white central area without increasing the height of the ft or hd divs. How do I achieve that? Many thanks! edit: see http://jsfiddle.net/PxabT/15/ which is a step forward by changing the borders to padding.

  • problem with logout script in php

    - by user225269
    I'm a beginner in php, and I am trying to create a login and logout. But I am having problems in logging out. My logout just calls for the login form which is this: <? session_start(); session_destroy(); ?> <table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"> <tr> <form name="form1" method="post" action="checklogin.php"> <td> <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"> <tr> <td colspan="3"><strong>Member Login </strong></td> </tr> <tr> <td width="78">Username</td> <td width="6">:</td> <td width="294"><input name="myusername" type="text" id="myusername"></td> </tr> <tr> <td>Password</td> <td>:</td> <td><input name="mypassword" type="text" id="mypassword"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Login"></td> </tr> </table> </td> </form> </tr> </table> My problem is, when I try to press the back button in the browser. Whoever user is using it can still access what is not supposed to be accessed when a user hasn't logged in. Do I need to add a code on the user page? I have this code on the user page: <? session_start(); if(!session_is_registered(myusername)){ header("location:main_login.php"); } ?> What can you recommend that I would do so that a script will prompt to enter the username and password again when a user clicks on the back button.

  • How to indicate 'missing' tags in XQuery?

    - by Stewart
    I have an XML file: $xml := <xml> <element> <text>blahblah</text> </element> <element> </element> <element> <text>blahblah</text> </element> </xml> I can use the query for $x in $xml/xml/element/text return string($x) This gives me a list blahblah blahblah with no indication that there is an element which has no element. What I'd like to do is use a query which, if there is no such element, returns, say "missing". How do I do this?

  • Pre-loading external files (CSS, JavaScript) for other pages

    - by Jason Young
    I'm curious if there is an efficient way to wait for the front page of a site to load, and then pre-load CSS and script files that I know will likely be needed for the other pages on the site. I want the front page of the site to be as fast as possible (lean and mean). It's likely that the user will not immediately click on a link. Since there will likely be some idle time, this seems like an opportune time to pre-load some of the external assets. Pre-loading should cause them to become cached. When the user does click on another page, the only request needed will be for the content and possibly some images, etc. Has anyone done this? Is it a bad idea? Is there an elegant way to implement it?

  • Pre-Populated Date in Text Field

    - by user2537332
    I am trying to pre-populate a text box with today's date, but for some reason, it keeps showing today's date as 5/30/13, which is a month behind. This code should just be pulling the local time so why is it a month behind? Here is my code, can someone please tell me why the current date is off...Please help, :) var dateToday=new Date(); function loadDate(){ var today=dateToday.getMonth() + "/" +dateToday.getDate()+"/"+dateToday.getFullYear(); document.forms[0].curDate.value=today; } function orderReady(orderTime){ dateToday.setDate(dateToday.getDate()+orderTime); var ready=dateToday.getMonth()+"/" +dateToday.getDate()+"/"+dateToday.getFullYear(); document.forms[0].puDate.value=ready; } <body onload="loadDate();"> <p>Today's Date<br /> <input type="text" name="curDate" size="50" /><br />

  • Isotope.js help: Changing item image after sorting

    - by user3643081
    This is a general question on how to go about building a project I have in mind, and the best way to set off on the right foot. I am fairly new to JS, please be gentle. I want to use isotope.js (or a similar script) to display a page with multiple items (about 30 different plants found in a garden) and the ability to sort them by seasons of the year + "what is most beautiful now" + and "view all" (a total of 6 categories) . On load, or when sorted by either "what is beautiful now" or "view all", I need each item to reflect the image of the current season we are in. When sorted by season, I need those "current" images to switch over to a designated seasonal image of that plant. Therefore, each sortable item will ultimately have 4 different versions with 4 different images in the background ready to surface when plants are sorted. (perhaps 5 if it makes more sense to have a "current" version besides the 4 seasonal versions.) My question: what approach can I take to achieve this effect in a manageable way? Can isotope apply a class to items sorted? Assuming it can: Should each item have 4 inline images, each with a css class, that I then control by using display:inline; and display:none; properties from my stylesheets? (I worry that this approach would significantly increase load times) Would it make more sense to create a blank dummy div who's background I control similarly to the example above -relying mostly on CSS. Or is there some other way involving JS I am overlooking? Any help would be appreciated. Examples of what you suggest would be immensely helpful.

  • How are table headers supposed to be used?

    - by stevebot
    Hi, Recently I saw some code like this: <tr> <th> Some label: </th> <td> <input type="text" value=""/> </td> <th> Another label: </th> <td> <input type="text" value=""/> </td> </tr> I am used to table headers being used like <tr> <th> Some label: </th> <th> Another label: </th> </tr> <tr> <td> <input type="text" value=""/> </td> <td> <input type="text" value=""/> </td> </tr> How are table headers supposed to be used? The first example above, lead me to some pretty funky formatting issues, and it seems like in example 1 <label> should be used in place of <th>.

  • How do I cancel a text selection after the initial mousedown event?

    - by cwillu-gmail
    I'm trying to implement a pop-up menu based on a click-and-hold, positioned so that a (really) slow click will still trigger the default action, and with the delay set so that a text-selection gesture won't usually trigger the menu. What I can't seem to do is cancel the text-selection in a way that doesn't prevent text-selection in the first place: returning false from the event handler (or calling $(this).preventDefault()) prevents the user from selecting at all, and the obvious $().trigger('mouseup') doesn't doesn't do anything with the selection at all. This is in the general context of a page, not particular to a textarea or other text field. e.stopPropogation() doesn't cancel text-selection. I'm not looking to prevent text selections, but rather to veto them after some short period of time, if certain conditions are met.
