HTML - To Check The Type Of Data Passed As An Argument In A Function
i am trying to make a html program in which theres a function which will take a single argument and then it will check the type of argument passed i.e whether it is an integer type or string or float and print the same.I tried making it and cud do it by using "on button click".but i am not getting how to to it without "button onclick".i just want to print the type of data passed without any button onclick.
can anyone here help me with it.heres what i did: <html> <head> <script language="JavaScript"> function datatype() { } function check(arg) { document.write(typeof(arg)); } var data=new datatype(); </script> </head> <body> <input type="button" onclick="(data)" value="Object"> <input type="button" onclick="check(5)" value="Number"> <input type="button" onclick="check('Hello')" value="String"> </body> </html> Similar TutorialsIs there a connection between a form's "submit button" <input type="submit"> and it's "action/method/enctype" attributes <form action="url" method="post" enctype="text/plain">? Is there a difference between "submitting" a form and "posting" a form or is it all interconnected? Does the form's "action/method/enctype" attributes have to be set to allow the "submit button" to do anything? Do the "action/method/enctype" attributes have to be triggered by a "submit button"? Once I understand how this all works, I want to run some checks on user entries/selections in a form when the user clicks the submit button. These checks will be carried out by a JavaScript function. If there are problems with the user's selections/entries I want to; 1) suspend submission/posting 2) alert the user to the errors they have made via an alert box 3) allow the user to make corrections, then they click submit again 4) test the user's selections/entries again 5) if user's selections/entries are now OK, submit/post the form data or if still not OK go back to step 2 above. Any hints on how to do this? Maybe I should forget the submit button and use a command button? Is there a "submit" method I can place in a JavaScript function? Conflict between Mime Type and Document Type... Morning - I have recently been learning CSS and have been upgrading my site to Semantically correct code. The first templat I am building is the following page http://www.colletts.co.uk/colletts_n...ndexflash.html and validates here validates... sort of. Should I be worried about the mime type, what effect will this have on the page. If I follow the instructions and change the file extension to xhtml all hell breaks loose - http://www.colletts.co.uk/colletts_n...dexflash.xhtml IE Error - can't open thios document etc... What am I doing wrong??? Best, Mas Hi I am trying to implement jQuery hovercard as specified he http://github.com/rrrene/tipsy.hovercard This code as an example uses data-url which specifies a html page that contains the html to use in the hovercard. But my site uses Smarty classes and so the images i want to show in my hovercard have already been found and the links loaded into variables. How do I turn this html Code: <a href="some.html" rel="hovercard" title="loading..." data-url="tip.html">Hovercard w/ AJAX Flavour</a> into a statement that reads from a bit script that can load using the variables already populated? I cant find anything on the web about data-url. Its all data:URL. Thanks Darren Dear all, I am new to html. If I create a html form, after a visitor input the data to the form and click submit, this form will send data to another web page with the form data, e.g. http://www.mydomain.com/confirm.html...m&name=someone What is the html command to display the passed form value in the destination page? e.g. If I want to show the following: Hi, someone, You subscription with email abc@yahoo.com has been received. Thanks! Hello, I'm a newbie in HTML Development. Could someone please help me on this? I'm calling another HTML ie. http://www.mywebsite.com/Page2.html?ID=1234 Basically, I'm on Page1.html and there's a link there that I'm referencing to call Page2 but passing a variable of ID=1234. How can I use this ID=1234 in Page2's vbscript? In my Page2.html, I have a vbscript section and I want to get the passed variable. How can I do this? What should I put in: <script type="text/vbscript"> strProductID= ??????? ... </script> Thanks in advance! Hi all I am passing some values from page1 to page2 using javascript function as shown window.location.href = "DeviceDatanew.html?row=" + i1+ "&total=" + 10; These values I want to display in page 2 table which already has some values with 2 cells empty. how to display the passed values through javascript in those empty cells. Ok I am getting some validation errors on my site and at least some of them appear to be because I am using xhtml in an html strict doc. So which is better.... to fix the errors or use something other than the html strict doc type. fyi-here is the site: http://www.h51school.com/1/home_page.asp Thanks~ Hi I see a lot of these type of borders on the internet, even when signing up on this site. How can I do this myself? I thought I had once knew how to do this this in Dreamweaver but am not able to find it anymore. Thanks basicaly what the title says i have no idea what they do. Please explain in nooob terms Hi, I am having a huge problem When ever I design a page everything looks great. When I publish it and look at it from other machines the type appears fuzzy or not sharp.

How can I detect the mime type of a file given the filestream or any other solution to this problem Thanks. Hello, I'm new to html andscripting etc.... I'm trying to create a game online that will start off as text.I'm trying to make the character creation portion of my site easy to use and figure out. I've been searching online the past few days trying to figure out how I would go about this and am at a loss as to what it is I'm specificly searching for in regards to learning more about what it is i'm trying to do. I have found a site that has the features that would be perfect for what it is I'm looking for but do not know what this type of coding is called. Basicly this is the site that I found with the features. http://linklost.com/occ/ .What I'm wanting to know exactly is how I would go about inputting the code for when I click on the radio buttons information and text shows up in a box next to it.Obviously no one can create this code for me, I just need to know the "type" of coding I suppose so I can go research it and try to learn it myself. I thank you ahead of time for any help I can get in regards to what probably is a simple answer to most. Brandon Hi, i've been banging my head against the wall trying to find a solution, and have eventually given in..! I'm creating an html email that has an image in it. Easy When that email is received and the user prints, it replaces the image with another more print friendly version. Easy using media:print in a style. However, when the user then replies to the email, all of the <style> in the <head> is wiped and the large un-printer friendly image remains. The only solution would be to put all styles inline within the <body>. So the question..! Any ideas how to replicate this process only coding within the body? thanks, J How would I make a search-type form that would insert what the user typed in a text box into a web address and go to that address? (for example, if they type 'help' and click the submit button, it would go to the page "http://www.websitename.com/help.html") I know the general form code, but I can't figure out if I would use a tag in the 'onSubmit' portion, or use javascript, or something else altogether. |
