If you call the below code, it will incorrectly print "true, false" when it should be "true, true". WHy is that? How do I fix this?
Code: isCapitalLetter = /[A-Z]/g;
//Incorrectly alerts "true,true"
alert( isCapitalLetter.test( "lineHeight" ) + "," + isCapitalLetter.test( "lineHeight" ) );
Either I'm having a really dim Friday, or something strange is going on. I'm trying to add a method to the Validator plugin, using the following regex:
[Code]....
I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
Code JavaScript:
if(document.getElementById('RegisForm_Username').value == /[^a-zA-Z 0-9]/g)
{
your username must be alphanumeric (consisting of the letters A-Z or numbers 0-9) and cannot have any special characters.");return false;}
This is driving me freaking crazy. I have a RegExp, and a String. When I alert RegExp.test(String), I get "true." Sweet. Then I run String.replace(RegExp, ""), in an attempt to get rid of whatever was matched. But that does not change the string at all.
Am I misunderstanding replace, or what?
I have a regex here:
Code:
var NameValidator = {
first_middle_last_with_first_middle : function(txt){
[code]....
I created a custom validation like this <script type="text/javascript">

Today I've tried to create simple hover effect on a <div>: if the cursor is over the box, the background-image css property of the div is modified. On the HTML side, a <div> with an id:

I'm new to ajax. I've made a script that should return results from database but it keeps telling me just undefined. Code what I have:
Code:
var ajax = null;
function showRes(wut) {
if(wut.length == 0) {
document.getElementById("results").innerHTML = "";
return;
} if(window.XMLHttpRequest) {
// IE7+, ff, chrome, opera, safari
ajax = new XMLHttpRequest();
}else if(window.ActiveXObject) {
// retards
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert("Your "browser" does not support AJAX!");
return;
} var url = "search.php?q=" + wut;
url = url + "&sid=" + Math.random();
ajax.open("GET", url, true);
ajax.send(null);
document.getElementById("results").innerHTML = ajax.reponseText;
}
I've got a list in which each item has a link that shows and hides a div, and also changes text of the the link. I want to write the code like this:
$(".log a").click(function() { $("#panel-" + $(this).data("build_id") + ":hidden").trigger('showLog'); $("#panel-" + $(this).data("build_id") + ":visible").trigger('hideLog'); return false; });
... but that doesn't work. It seems as though if the first selector returns no elements that the 2nd line is not executed. I might be wrong about the diagnosis, but the symptom is that I can show the log, but can't then hide it, whereas if I start with all the panels visible and remove the first selector, the hideLog event is triggered as expected.What does work is this:
$(".log a").click(function() { var panel = $("#panel-" + $(this).data("build_id")); if (panel.css("display") == 'none') { panel.trigger('showLog'); } else { panel.trigger('hideLog'); } return false; });

In the below code, the alert message returns in one instance: 'someAnimal is [Mammal "Mr. Biggles"]' I don't understand how this is possible. We pass as an argument 'Mr. Biggles' to the Mammal constructor. Then assign it to the object name property. But then it ends there. There is a function called toString which will return the alert. But the toString function is not being called like this: alert('someAnimal is '+someAnimal.toString()); If it was like how it is above, it would make sense to me but now it makes no sense to me because I don't see where that toString() is being called - I only see that it is prototyped to the Mammal object.
Code:
function Mammal(name){
this.name=name;
this.offspring=[];
}
Mammal.prototype.haveABaby=function(){
var newBaby=new Mammal("Baby "+this.name);
this.offspring.push(newBaby);

I have been a mainframe programmer for over 20 years - I have a new project that requires browser pages written in JavaScript. I currently begin with a HTML page that assigns the values retrieved from a third party vendor's API to an array. I pass this array to another page to build a table full of links - when a client clicks on one of the links, two variables are put into yet another array and a third page is called, successfully passing the required data. Ultimately page 1 and page 3 will be .asp pages so that additional third party vendor API's can be called. The problem is this: after the third page is called from the second page, it displays for a second and then returns to the second page. When I click back I can see the third page, followed by the second page, and finally the first page. My question is this: why is the third page not displaying in the browser? I'm sorry if I have not posted this correctly as I really am a mainframe programmer and this is my first time doing anything code related with web pages
View 8 Replies View RelatedI'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

Something like:

I am using Jquery ajax in JSP and I am populating divs using the callback method of jquery ajax. To enable jquery/js for the populated divs I am using getScript() function so that the jquery methods get bind to the newly generated divs/html tags. Now when I am doing this multiple times the js file is getting loaded multiple times and the next time when I perform an event lick onclick or onchange, two ajax calls are going to the server which is causing lot of inconvenience. Now, my question is that is there any way to unbind the old js file either in the head tag or the one cached by using getScript function.
View 1 Replies View RelatedI have a page that has a box where announements can be seen. What I want is that when the page loads a div containing some announcement text should show up within this box. The divshould remain within the box for about 10 seconds, whereafter it should start sliding to the left and eventuallydisapper. Butif the user during the sliding decides to Hover or clickwithin that div then the sliding should stop andthe div should move back to its initail position (so that the whole text can be read again). The div shouldnotbegin any sliding process as long as theuser is hoveringwithin the div. Howeverif the user hover out of the div then the sliding proces should begin again.
What I'm trying to achieve is to havea annoncement to show up in this box, only for 10 seconds,whereafterit should disapper (by sliding away). However if the user wants to reads the annonuncementhe should be able to do so, by hovering that announcement. And whenthe user hasfinished reading he can just hover away and the announcement will disapper within few secounds. I have done some work here and there. I have used the slider method from jqueryui and the hover methods and the initial sliding process when the page loads, but putting them all to gether is not going good.
What I am wanting to do is have my form open up a new part of the form when the previous sections are filled out. i.e name field shows, when it has content, the next field opens up for it to be filled out, and so on.
