  • observing multiple select menus with prototype

    - by snaken
    Hi, I want to observe multiple select menus and respond to their changes using prototype but only the first menu seems to be observed. This is my code: $('product_options').select('select').invoke("observe","change",optchange); If there are - for example - 3 selects within product_options then it only observes the first, i thought it might be because of invoke so i then tried this: $('product_options').select('select').each(function(sel){ $(sel).observe("change",optchange); }); Still doesnt work though, any ideas whats wrong?

  • Equivalent of object using literal notation

    - by brz dot net
    See following class: function availItem(xs, s, m, l, xl) { this.xs = xs; this.s = s; this.m = m; this.l = l; this.xl = xl; } How can I declare the above class using JSON? I think It should be in following manner but problem is to pass argument. var availItem = { xs : xs, s : s, m : m, l : l, xl : xl } I want to use both in same manner like var obj =new availItem(xs,s,b,l,xl);

  • Unexpected token ILLEGAL with jQuery

    - by Bram Vanroy
    So, I have a website with an autoFontSize script (Got it from stackoverflow, but slightly edited it too loop over each div with that specific class) (function ($) { $.fn.textfill = function (options) { this.each(function () { var fontSize = options.maxFontPixels; var ourText = $('h2 a', this); var maxHeight = $(this).height(); var maxWidth = $(this).width(); var textHeight; var textWidth; do { ourText.css('font-size', fontSize); textHeight = ourText.height(); textWidth = ourText.width(); fontSize = fontSize - 1; } while ((textHeight > maxHeight || textWidth > maxWidth) && fontSize > 16); }); return this; }; })(jQuery); $(document).ready(function () { $('.fotonode.fotopagina').textfill({ maxFontPixels: 30 }); });? And a (simplified) HTML structure: <div class="fotonode fotopagina"> <h2><a href="#">Testing Title</a></h2> </div> For some reason this doesn't work (neither locally nor live) BUT it does work on JSfiddle: http://jsfiddle.net/Yb9yj/ I read somewhere that this can cause problems. I copied the code from jsfiddle to my file, so maybe I have (unintentionally) copied some white spaces that shouldn't be there or something. I don't know. But how can I solve this then?

    - by Nirmal
    Is there any way to make only a non-transparent portion of an image to trigger mouse-over event? If the mouse travels to the transparent area, the mouse-out should be triggered and the script should listen for any mouse-over event on a layer underneath the image. Is it possible? Thanks for any input.

  • Problem accessing private variables in jQuery like chainable design pattern

    - by novogeek
    Hi folks, I'm trying to create my custom toolbox which imitates jQuery's design pattern. Basically, the idea is somewhat derived from this post: http://stackoverflow.com/questions/2061501/jquery-plugin-design-pattern-common-practice-for-dealing-with-private-function (Check the answer given by "David"). So here is my toolbox function: (function(window){ var mySpace=function(){ return new PrivateSpace(); } var PrivateSpace=function(){ var testCache={}; }; PrivateSpace.prototype={ init:function(){ console.log('init this:', this); return this; }, ajax:function(){ console.log('make ajax calls here'); return this; }, cache:function(key,selector){ console.log('cache selectors here'); testCache[key]=selector; console.log('cached selector: ',testCache); return this; } } window.hmis=window.m$=mySpace(); })(window) Now, if I execute this function like: console.log(m$.cache('firstname','#FirstNameTextbox')); I get an error 'testCache' is not defined. I'm not able to access the variable "testCache" inside my cache function of the prototype. How should I access it? Basically, what I want to do is, I want to cache all my jQuery selectors into an object and use this object in the future.

  • Trying to perform a series of actions on page unload, but the pages unloads too fast to finish them.

    - by user138821
    I have a series of actions I want to perform on page unload. Namely if a user is editing an input field, and they refresh or close browser or leave page, I want to save the contents of the field. The actions don't include an AJAX call, so I can't just make it synchronous. It's actually saving to local storage, but the page unloads before the storage can take place. The code is correct, if I add an alert to the actions, the delay allows the rest of the code to finish before it even displays. Any ideas? Thanks!

  • How do i view the local database version in safari on the iphone?

    - by ~potsed
    I am trying to see the localDatabase version from my iPhone in safari but it is not displaying, according to the docs i am supposed to be able to do this: var db = openDatabase('dbShortName', '', 'dbLongName', 1000); alert(db.version); and it should alert the current version number. It does not. It works in Chrome and safari for the desktop but not the iPhone. Does anybody have some idea why? My next option is to store the version in a separate table, but I would prefer to use the built in system. Thanks in advance.

    $.ajax({ url: "plugin.js", dataType: 'script', cache: true, success: function() { alert('loaded'); }}); 1) I can't get the script to load, probably due to incorrect path, but how do I determine the correct path?

  • Assigning function within function object without invoking the function itself.

    - by webzide
    Dear experts, I am trying to assign an function within an function object property without actually invoking then function itself. for instance, I have the following function object class definition function objectOne(name, value, id){ this.name=name; this.value=value; this.id=id; this.methodOne=methodFunction(this); } the last line this.methodOne=methodFunction(this); I want to pass the current object to the function but at the same time i don't want to execute the function right now. But if I do it this way without the bracket this.methodOne=methodFunction then the argument of this object would not be passed as a parameter to the function. Is there a way to work through this. Thank you in advance
