pageload

问题 I have created and validated an ePub 3 which I am currently testing. I am using a fixed layout.. <meta property="rendition:layout">pre-paginated</meta> <meta property="rendition:orientation">portrait</meta> <meta property="rendition:spread">none< /meta> It works nicely, however multiple pages seems to load and run at once when testing in different readers. I'm using jQuery's document ready to kick things off and play audio, run animations, etc. When testing in iBooks I open the book to page 1

问题 Is it possible to find out which javascript files are NOT used on a web page without having to add console logs or debug or removing them to see if things break? I'm looking for a tool, or a command line script or firefox plugin etc. For example, let's say I have these included in the header: <script type="text/javascript" src="js/jquery.js"></script> <script type="text/javascript" src="js/functions.js"></script> <script type="text/javascript" src="js/validation.js"></script> <script type=

问题 On my web page, almost all the elements (which are divided into panels/divs) are created dynamically only after the user selects one of two choices (show this or show that). After a form submission, though, the form returns to its original pristne/austere state. And so, I have to recreated those pieces, like so, in the code-behind's Page_Load() event: if (Page.IsPostBack) { GenerateSection1(); GenerateSection2(); GenerateSection3(); GenerateSection4(); GenerateSection5(); } However, this

问题 I have a button on my page and and few textboxes which alters their context on page_load event. when I open the page for the first time it loads random data from a database to textboxes with a function in pageload and also I create those textboxes dynamically. what I want is to make some changes on textboxes texts and click the button than send new context of textboxes to database. But when I click on button, PageLoad event fires again and It regenerates the textboxes and the context of them

问题 I am having a strange problem. Here is the scenario Here are my files: Project1.aspx Project2.aspx They are set up the exact same, including their Page_Load functions: Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load If (Not Page.IsPostBack) Then setPrevIndex(-1) ... End If End Sub They are both set up this way. Here is where I am running into a problem. When I navigate to either of these pages, i need to make sure that prevIndex is set to -1 (via the

问题 I've been looking for something very simple: How to make a side navigation expand with animation on page load , but all the tutorial websites I usually go to don't seem to have it. The closest I could find is this jQuery sample: http://codeblitz.wordpress.com/2009/04/15/jquery-animated-collapsible-list/ I've managed to strip down the list like so: <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(function(){ $('li') .css('pointer','default')

问题 When I load a page with a hash tag in the URL, the page loads and then jumps to the anchor tag. Is there any way to prevent this "jump", either by loading the page directly to the anchor tag or at least making the scrolling smooth? I see this problem in Chrome and Firefox, but not IE. 回答1: If you're still experiencing the jumping issue, you could something with jQuery: //Use a RegEx pattern to search for an id, if present var pattern = new RegExp('\#(.*)'); var id = pattern.exec(window

问题 In the pageload i populate a dropdownlist like this: protected void Page_Load(object sender, EventArgs e) { string buildingTypeSoldier = "soldier"; var soldierBuilding = from b in dc.Buildings where b.buildingtype == buildingTypeSoldier select b.buildingname; ddlSoldierBuildings.DataSource =soldierBuilding; ddlSoldierBuildings.DataBind(); } But when i then try to set the text of a label on the same page to the selectetitem.text i only get the first item in the list, not the item i selected. I

问题 It is said that Javascript code should be all placed at the end of HTML file, so that the page content is shown first, for the user to see something (so that the user is satisfied to see something instead of waiting another 12 seconds, for example). But to better encapsulation of the HTML and match Javascript code, such as an "Image Carousel", then usually the HTML and Javascript is placed in one single file, so there are Javascript code blocks all intermixed with HTML code throughout the

问题 Here the code behind... I'm trying to retrieve this control so I can add items to the drop down list (I'm retrieving the Role Groups to add to the drop down list in the code-behind) Protected Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim DDRoleGroups As DropDownList DDRoleGroups = FormView1.FindControl("DDRoleGroup") End Sub Here's the FormView: (I took out most of the fields so it's easier to read) <asp:FormView ID="FormView1" runat="server
