Hidden - Retrieve Information By Downloading The Source In My PHP Program
Apr 16, 2010
The link below is the result of a product search on a website. It displays 2 results. However, the actual results (picture & information) that are displayed on the web page are not present in the "Page Source".
For example, if you search the page source for the string '860723' (which is one of the product numbers visible on the web page) it is not there. What is going on here? It looks to me like dummy images & information in the HTML are first loaded by the browser, and then that dummy info gets replaced by the real information via a javascript function. Is that what's going on?

I'm trying to retrieve that information by downloading the source in my PHP program. The problem is that the information I want isn't present in the source. It stands to reason that the information is somehow being sent to the browser because I can see it..
i am developing a web application in which i have to retrieve the user browser and platform information. i am using javascript to get this information and tryin to pass these values to the html hidden form element. pasting a brief code from my application.
This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.
Here is the script: Code: function flip(pizzatype) { if (pizzatype.value == "Veggie Special") { document.forms["pizzaform"].topping.value = "veggies"; } else if (pizzatype.value == "Meat Special") { document.forms["pizzaform"].topping.value = "meat"; } else if (pizzatype.value == "Hawaiian") { document.forms["pizzaform"].topping.value = "hampineapple"; }}
The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement. if(pizzatype.value == "veggiespecial")... Shouldn't it be just (pizzatype == "veggiespecial")? Why does it have to be pizzatype.value? Where the heck does the .value come from???
Let me give an example: javascript: var myvar=10; function myfunc(){}; void(0); After excuting the above js source code in the address bar of my browser, I can use window.myvar and window.myfunc() to access myvar and myfunc. This indicates that the above "address-bar javascript code" must have been stored somewhere in the current page.
My question is: where is the "address-bar javascript code" stored in the current page? or equivalently, is it possible to retrieve the "address-bar javascript code" by using some other javascript codes?
I checked document.childNodes and document.documentElement, but cannot find the javascript source code. Maybe the source code is stored in the window object? How to retrieve it?
I am attempting to read XML information from a remote source into a javascript array. Upon retrieveing the XML, I load it into array by sections. I am doing this with the following code:
I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.
<html> <script type = "text/javascript"> function square(form)
I got some code that loads divs from other web pages into a particular div in my main page. In other words, I click on a button, and this tells jquery to load afragment of a particular page into my main page. For instance if I have 5 web pages onrock stars, I could have 5 buttons, and each button could load one rockstar's biography into a div on the main page (and replace whatever was there before). This works, and I do see the content that it loaded. But when I do 'view source' in IE, I do not see that content (the bio of the rock star). Another clue that this content is not really there, is when I try and run some code on that content. The content (from those external pages) have divs with specific names, and I try and make them into collapsible panels by running the following short function:
I have a following problem: from time to time an attack on my page is performed, overloading the server. The administrators had to limit the access to the page to some domains only. I would like to keep the page open for everybody.
Probably I should introduce a JavaScript/CGI driven form and let user to copy some letters etd. before letting him entering the page.
I am sure there are many solutions to this problem around, but I don't know what to search for. Can you give me some tips where to start?
I think the attacs are just casual, there are no real reasons why should anybody try to copy or destroy the page (no commerece, no money to loose or gain), so probably I should start with something simple.
Is it possible to use javascript to trigger download of some text on the website? For example, if I have some text in a Div that I want the user to be able to download. Can the text be downloaded as a text file then?
i don't know so much about jquery so just i use them with indication from their web site. so my problem is how can i use multiple source of jquery without one source stop the other,and that what i need:
recently i noticed that all of my embedded JavaScript code and external style sheets are being shown IN "view source."
this happens in all browsers ( IE, FF, Chrome, and Safari [windows]) ... oddly enough it only happens when viewing on my vista or win2k3 machines. is this something added to these OS's or the result of an installed program? has anyone seen this before?
When I clicked on the download link on the homepage (for both production and development version), the file opened in the browser (see image) but it didn't download.
I want to display a message like "In Progress" while my page is still loading. I am trying to achieve it by displaying a DIV, and then hidding it. My code is below. These images gets downloaded fast so hard to tell and test, but based on my logic you see any problem with this?
Currently I'm developping an application with RoR and jQuery. Is the first time I try to use this wonderful library so I'm still a little naive Right now I'm having a problem that I have no idea how to solve. Documentation, google, etc have been useless for me in this point (probably because I'm not searching the right terms) So I'm creating an invitation system: simply, a form where you put an email address and when you hit submit it makes an ajax call. The server should answer with some data such 'how many invitations the user have left', possible errors and (if in development enviroment) the url for the invitation (debuggin purposes), everything coded in json.
The problem is that sometimes when sending an invitation firefox pops me up with a download dialog suggesting to save an "application/json" file with all the data that the server processed. My jQuery script should be taking care of handling it and it is not. I have told Rails to render the answer in json format: render :json => message.to_json message is a hash with a format similar to {:error => "There was an error, sorry", :invitations_left => current_user.invitations_left} And I have also specified jQuery the type expected in the return of the call:
I have a feeling that the solution to my problem is stupidly simple, but crawling through Google has provided me with none.
I'm trying to handle the login process on one of my clients' site using the AJAX functionality provided by jQuery.
Here is the $.ajax() call in question:
$.ajax({ "cache": false, "complete": function() {
[Code]....
I have already set the Content-Type header of the response to application/json, which made no difference. I also tried text/html and text/plain, but in these cases Internet Explorer shows the JSON as HTML or plain text in the browser window... *sigh*
Googling also gave me the suggestion to just use text/plain and eval() the response myself, but I remember reading elsewhere that this is pretty unsafe. I am unsure on the specifics on this, though.
I have a website that I frequently visit (FWIW, Firefox 3.x is my browser of choice) with many image sources referring to URLs that end with "-thumbnail.jpg". However, for better image quality, I am trying to use Greasemonkey to replace all instances of "-thumbnail.jpg" in the source of images on this site with "-bigthumbnail.jpg". The closest I could think of was to somehow use getElementsByTagName and innerHTML.replace, but realized that innerHTML does not do HTML, only content.
Below is as far as I tried to get on my own,
var as,ae; as = document.getElementsByTagName("img"); for (var i = 0; i < as.length; i++) { ae = as[i]; ae.innerHTML = ae.innerHTML.replace(/-thumbnail/gi, "-bigthumbnail"); } })();
I am trying to get a simple set of Javascript tabs to work properly. I have just two tabs and I want to set up the script to have the second tab automatically hidden prior to reading the javascript code because right now it shows the contents of both tabs when the page is loading and then the second tab disappears after all the script has loaded.
I have the jquery script linked to on the page and here is the way my script looks to run the tabs:
Code:
I want to add something like style="visibility:hidden;" to the DIV that isn't shown on page load and have it added and removed as necessary when users click on the tabs. So basically I would like the generated code to look like this:
Specifically, assume I have a div tag of absolute dimensions. I need to figure out, first, whether or not the text inside the div tag is partially hidden by the overflow setting, and if so, what the hidden text is.
Is this even possible? Obviously, the rendering engine in the browser "knows" this information, but is it accessible through Javascript?
I have an assignment to create a program in JS but I have not read JS much more. So, for this assignment, can anyone help me to solve this assignment? Check attachment. [URL]
