Trigger click jquery not working

阅读更多关于 Trigger click jquery not working

问题 I'm figuring out why this simple script is not working: jQuery.noConflict(); jQuery(document).ready(function() { jQuery('.next_button a').trigger('click'); }); noConflict is necessary because I also load prototype/scriptaculous in this page. If I replace .trigger('click') with another function (es: .css(...) this works well. Only triggering seems to go broken. 回答1: How can I simulate an anchor click via jquery?

Force page scroll position to top at page refresh in HTML

阅读更多关于 Force page scroll position to top at page refresh in HTML

问题 I am building a website which I am publishing with div s. When I refresh the page after it was scrolled to position X, then the page is loaded with the scroll position as X. How can I force the page to be scrolled to the top on page refresh? What I can think of is of some JS or jQuery run as onLoad() function of the page to SET the pages scroll to top. But I don't know how I could do that. A better option would be if there is some property or something to have the page loaded with its scroll

Is the “async” attribute/property useful if a script is dynamically added to the DOM?

阅读更多关于 Is the “async” attribute/property useful if a script is dynamically added to the DOM?

问题 This question is sort of a tangent to Which browsers support <script async="async" />?. I\'ve seen a few scripts lately that do something like this: var s = document.createElement(\'script\'); s.type = \'text/javascript\'; s.async = true; s.src = \'http://www.example.com/script.js\'; document.getElementsByTagName(\'head\')[0].appendChild(s); This is a common way to add a script to the DOM dynamically, which, IIRC from Steve Souders\'s book \"Even Faster Web Sites,\" prompts all modern

How can I add FacesMessage during page load? Using @PostConstruct does not seem to work

阅读更多关于 How can I add FacesMessage during page load? Using @PostConstruct does not seem to work

问题 In a backing bean\'s @PostConstruct method, I make a call to an EJB which might return some messages that I want to display on the page via p:messages. However, even if I add the FacesMessages e.g. FacesContext.getCurrentInstance().addMessage(...), p:messages is not being updated with the FacesMessages. If I instead invoke the call to the EJB on an action from the page (say a user clicks a button on the page which invokes a method that calls the EJB and then adds the FacesMessage(s)), then

PHP echo vs PHP short tags

阅读更多关于 PHP echo vs PHP short tags

问题 Are they equal in safeness? I was informed that using <?=$function_here?> was less safe, and that it slows down page load times. I am strictly biased to using echo. What are the advantages/disadvantages? 回答1: <? and <?= are called short open tags, and are not always enabled (see the short_open_tag directive) with PHP 5.3 or below (but since PHP 5.4.0, <?= is always available). Actually, in the php.ini-production file provided with PHP 5.3.0, they are disabled by default: $ grep 'short_open'

问题 I am trying to check if web page is loaded completed or not (i.e. checking that all the control is loaded) in selenium. I tried below code: new WebDriverWait(firefoxDriver, pageLoadTimeout).until( webDriver -> ((JavascriptExecutor) webDriver).executeScript(\"return document.readyState\").equals(\"complete\")); but even if page is loading above code does not wait. I know that I can check for particular element to check if its visible/clickable etc but I am looking for some generic solution 回答1

Is there a cross-browser onload event when clicking the back button?

阅读更多关于 Is there a cross-browser onload event when clicking the back button?

问题 For all major browsers (except IE), the JavaScript onload event doesn’t fire when the page loads as a result of a back button operation — it only fires when the page is first loaded. Can someone point me at some sample cross-browser code (Firefox, Opera, Safari, IE, …) that solves this problem? I’m familiar with Firefox’s pageshow event but unfortunately neither Opera nor Safari implement this. 回答1: Guys, I found that JQuery has only one effect: the page is reloaded when the back button is

How to make JavaScript execute after page load?

阅读更多关于 How to make JavaScript execute after page load?

问题 I\'m executing an external script, using a <script> inside <head> . Now since the script executes before the page has loaded, I can\'t access the <body> , among other things. I\'d like to execute some JavaScript after the document has been \"loaded\" (HTML fully downloaded and in-RAM). Are there any events that I can hook onto when my script executes, that will get triggered on page load? 回答1: These solutions will work: <body onload="script();"> or document.onload = function ... or even
