  • How can I implement a jquery ajax form which requests information from a web api via a php request?

    - by Jacob Schweitzer
    I'm trying to implement a simple api request to the SEOmoz linkscape api. It works if I only use the php file but I want to do an ajax request using jquery to make it faster and more user friendly. Here is the javascript code I'm trying to use: $(document).ready(function(){ $('#submit').click(function() { var url=$('#url').val(); $.ajax({ type: "POST", url: "api_sample.php", data: url, cache: false, success: function(html){ $("#results").append(html); } }); }); }); And here is the part of the php file where it takes the value: $objectURL = $_POST['url']; I've been working on it all day and can't seem to find the answer... I know the php code works as it returns a valid json object and displays correctly when I do it that way. I just can't get the ajax to show anything at all!!

  • Can I not submit a form to a servlet from JSF?

    - by simpatico
    * Unable to find matching navigation case with from-view-id '/home.xhtml' for action 'MemoServlet' with outcome 'MemoServlet' I try to accomplish it through: <h:commandButton type="submit" value="add" action="MemoServlet"/> but all the tutorials in the world only do it with a bean, which i don't want. I've come across any navigation rule that accomplishes my request.

  • Submit to open up a popup window and carry through input data

    - by zac
    Hi, I have a input box on one page that on submit opens a new page with a longer form and the first field is populated with what was entered from the previous pages input box. So on page 1 there is this code: <form action="sign-up.php"> <input type="text" name="email" value="sign up for email" onFocus="clearText(this)" onBlur="clearText(this)" style="float: left;"> <input value='Submit' /> </form> Then on the sign-up page the receiving form grabs the string out of the url //<!-- Begin function getParams() { var idx = document.URL.indexOf('?'); if (idx != -1) { var tempParams = new Object(); var pairs = document.URL.substring(idx+1,document.URL.length).split('&'); for (var i=0; i<pairs.length; i++) { nameVal = pairs[i].split('='); tempParams[nameVal[0]] = nameVal[1]; } return tempParams; } } var params = getParams(); // End --> I would like to keep all of this functionality but it have it occur in a popup. I added this function to the submit: function myPopup() { window.open( "sign-up.php", "myWindow", "status = 1, height = 300, width = 300, resizable = 0" ) and the form becomes <form> <input type="text" name="email" value="sign up for email" onFocus="clearText(this)" onBlur="clearText(this)" style="float: left;"> <input onClick="myPopup()" value='Submit' /> </form> But it no longer appends the input data to the url string. Anyone have any ideas on how I can accomplish this?

  • JQuery Tabbed Nav Menu and PHP Forms Question?

    - by SlAcKeR
    I'm using a JQuery Tabbed Menu which holds different types of forms and when I select a different form located under a different tab and submit the form the tab will jump to the default tab instead of the current tab the form is located in. I was wondering how would I go about fixing this so that when the form is submitted the current tab is still selected, is it the JQuery or PHP problem? Here is the JQuery. $(document).ready(function() { //When page loads... $(".form-content").hide(); //Hide all content var firstMenu = $("#home-menu ul li:first"); firstMenu.show(); firstMenu.find("a").addClass("selected-link"); //Activate first tab $(".form-content:first").show(); //Show first tab content //On Click Event $("#home-menu ul li").click(function() { $("#home-menu ul li a").removeClass("selected-link"); //Remove any "selected-link" class $(this).find("a").addClass("selected-link"); //Add "selected-link" class to selected tab $(".form-content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the selected-link tab + content $(activeTab).fadeIn(); //Fade in the selected-link ID content return false; }); });

  • Code is exectuting but the view is not loading when called form a function?

    - by wolverine
    I have a viewBased application with the viewController class mainView. In it I am loading various views(different nibs) depending upon certain actions that I do. I have added a popoverController with a barbutton in the mainView. Its intialized with a tableviewController class named popClass. When I select certain row in the popover, I want the view in my mainView to load someother view(as I do when i do certain actions). For that I have written a function in mainView Controller class and is calling it from the popOver class. Function and the lines of code are executing but nothing is happening. Even the log lines are printed but no action takes place. What is the problem? OR is there anyother way to make the view change in mainView by using the popover?

  • How can I paste an image from the clipboard into a web form?

    - by dr. squid
    I found this question, but the question is about how to get an image from the clip board into a wyziwyg editor! My question is "How can I paste an image from the clipboard into a field (what field is not that big issue as long as it works)", and then sent to the server. Jira has this functionality, so it should be possible! Any ideas on how to do this? Just to explain the complete workflow; I would like to have a plave to multi upload images, where the paste from clipboard also is an option. The upload will be some ajax of some sort, bt is not important in this context! Thanks

Here is the old stuff: Plain old html form tag like this: <form name="someForm" action="somewhere" method="post"> <input name="param1"/> <input name="param2" /> </form That is sending data by post to a location specified in the action attribute of the form. The new stuff: <h:form id="paymentForm"> <h:panelGroup> <h:inputText id="param1" value="#{facesView.param1}" ></h:inputText> <h:inputText id="param1" value="#{facesView.param2}" ></h:inputText> <h:panelGroup> <h:commandLink>Submit</h:commandLink> </h:panelGroup> </h:form> This other new stuff doesn't work. 1.How do I specify to this h:form where to go(like setting action in old html) because I need it to go to a totally new url. 2.how to pass params with POST? Any help is appreciated. Milos

  • How do I get only two form fields to show instead of all 5 on initial page load? CSS

    - by marcamillion
    Here is the implementation: http://jsfiddle.net/AdQfB/2/ If you notice, when you click 'Login' or 'Register' before entering anything, you should see a few fields disappear and re-appear respectively. I would like for this page to display the view of just the two fields on the first load (rather than the current 5 it shows on first load), then when the user clicks the 'register' link, it shows the other 3 - for a total of 5. How do I do that? Thanks

  • Making "helper" text in a form be a different color then typed text.

    - by aslum
    <input name="phone" type="text" id="phone" value="Phone #" onfocus="value=''"> I've got two problems here. The main one is I would like the helper text (in this case "Phone Number") to be a different color then the inputted text from the user, to make it easier for the user to differentiate between filled and unfilled fields. The second is that with this methodology (onfocus="value''") if you mistype something in a field and come back to it you have to retype the whole thing which isn't really acceptable.

  • Wasteful Ajax Page Loading

    - by Matt Dawdy
    I've started a new job, and the portion of the project I'm working has a very odd structure. Every pages is a .Net aspx page, and it loads just fine, but nothing is really done at load time. Everything is really loaded from a jquery document.onready handler. What is even more...interesting...is that the onready handler calls some ajax calls that drop entire .aspx pages into divs on the page, but first it strips out several parts of the the returned page. This is the "magic" script the previous programmer ran on all the returned html from his ajax calls: function CleanupResponseText(responseText, uniqueName) { responseText = responseText.replace("theForm.submit();", "SubmitSubForm(theForm, $(theForm).parent());"); responseText = responseText.replace(new RegExp("theForm", "g"), uniqueName); responseText = responseText.replace(new RegExp("doPostBack", "g"), "doPostBack" + uniqueName); return responseText; } He then intercepts any kind of form postback and runs his own form submission function: function SubmitSubForm(form, container) { //ShowLoading(container); $(form).ajaxSubmit( { url: $(form).attr("action"), success: function(responseText) { $(container).html(CleanupResponseText(responseText, form.id)); $("form", container).css("margin-top", "0").css("padding-top", "0"); //HideLoading(container); } } ); } Am I way offbase in thinking that this is less than optimal? I mean, how does a browser take out the html and head and other tags that don't have anything to do with what you are really trying to drop into that div? Also, he's returning things like asp:gridview controls, and the associate viewstate, which can be quite large if his dataset is big. Has anyone seen this before?

  • why IEEE floating point number calculate exponent using a biased form?

    - by lenatis
    let's say, for the float type in c, according to the IEEE floating point specification, there are 8-bit used for the fraction filed, and it is calculated as first taken these 8-bit and translated it into an unsigned number, and then minus the BIASE, which is 2^7 - 1 = 127, and the result is an exponent ranges from -127 to 128, inclusive. But why can't we just treat these 8-bit pattern as a signed number, since the resulting range is [-128,127], which is almost the same as the previous one.

  • In ASP.NET MVC Should A Form Post To Itself Or Another Action?

    - by Sohnee
    Which of these two scenario's is best practice in ASP.NET MVC? 1 Post to self In the view you use using (Html.BeginForm) { ... } And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Edit(EditModel model) 2 Post from Edit to Save In the view you use using (Html.BeginForm("Save", "ControllerName")) { And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Save(EditModel model) Summary I can see the benefits of each of these, the former gives you a more restful style, with the same address being used in conjunction with the correct HTTP verb (GET, POST, PUT, DELETE and so on). The latter has a URL schema that makes each address very specific. Which is the correct way to do this?

  • Why would the same web form control render different "onclick" logic based on the page structure?

    - by zk812
    It was hard to title this question. :) I have a user control that is used to display a list of lookup items in my database and a delete button for each item (Editor User Control below). The delete button has an onClientClick event used to display a confirmation dialog in JavaScript. On page one, the confirmation pops up and functions correctly. The overall structure is: Master Page Page Editor User Control List of items with delete button On page two, the confirmation pops up but regardless of the answer, the page posts back anyway. The structure of this page is: Master Page Page User Control Editor User Control List of items with delete button For some reason, this makes a difference in how the delete button is rendered. Page one: <input type="image" name="ctl00...RequestTypesDataList$ctl01$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(1);" /> Page two: <input type="image" name="ctl00...RequestTypesDataList$ctl07$ctl01" src="Images/Disable.png" alt="Delete" onclick="return ProcessDeleteCommand(2);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$ContentPlaceHolder1$RequestCreator1$RequestTypeEditor1$RequestTypesDataList$ctl07$ctl01&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" /> Does anyone know why page two renders WebForm_DoPostBackWithOptions after my JS check? It's causing the postback regardless of the confirmation choice.
