I want to email a web page through javascript. Its enough to open the outlook new mail option. I try to move a Here i am using mailto: option in html.
Actually i am try to create a dynamic email template and want to send that template in html format.
Its showing error "comment line argument is not valid. verify the switch you are using"
please get me the solution.
Javascript can't send e-mails. Your best bet is the e-mail me syntax. There is a convention that most browsers suppors that lets you set the contents of various attributes as well.
e-mail me
It will have to be URL encoded, and as far as I know, there is no reliable way to pass HTML. You have to assume plain text emails.
You really need the server's help to make this easier.
1) Have the server make an XMLHTTP request to the page that generates the HTML you want. Grab it and make it the mail body.
or -
2) Grab the innerHTML, stick it in a hidden textarea and post it back to the server. Use the posted form field in the mail body.
You need to do this server-side, not client side. Outlook is not going to allow you the control you need to use a template. And for good reason - you wouldn't want websites taking control over your Outlook and sending emails.
If you can tell us what server you're using, we can show you how to send the email server-side.
There are security restrictions which stop it working directly. Yes if you wanted Outlook specifically, you could start messing with ActiveX - but that is fiddly and limited certain operating systems , installations, and security settings.
It is much better to use a mailto: URL. This is then cross-platform, and supports any default mail client.

I have a scenario where I need to send an email using c#, which could be easily done using SMTP, but the challenge is to incorporate web service in the html mail, hence i have used java scripts inside mail body to access the web service when a button click is raised.
As a html(Web Page), it works perfectly good but then when i send a mail and try with the click of a button in my mail, the onclick not raised the jscript and hence no action has happened and it was actually disabled.
I checked with the firebug(in firefox) in the particular html tag, to my surprise the jscript tag was not present there hence the event was not raised. My question is can we access web service in html email? and don't JScripts works on Gmails?
Does the html email do only the redirecting, using href... To my experience i have never got any mail which uses java scripts(like click of a button zooms the image in the same page, which is very much possible in html,asp pages). Thx in advance...
Apart from struggling to understand the question, Javascript won't work in most mail clients. Deliberately disabled.
You can't automatically call a web service from an e-mail letter. You have to create an URL for the recipient to open, and let them access the web service from a web page in the browser.
JavaScript, and any other third party communication method for that matter, is disabled in any reasonable e-mail client by security reasons.
I'm not aware of any email client or web mail service that will execute JavaScript embedded in an HTML email.
Limit HTML use in emails to formatting. If you need an web application, then link to it instead.
I've been looking for better ways to secure my site. Many forums and Q/A sites say jquery variables and HTML attributes may be changed by the end user. How do they do this? If they can alter data and elements on a site, can they insert scripts as well?
For instance I have 2 jquery scripts for a home page. The fist is a "member only" script and the second is a "visitor only" script. Can the end user log into my site, copy the "member only" script, log off, and inject the script so it'll run as a visitor?
Yes, it is safe to assume that nothing on the client side is safe. Using tools like Firebug for Firefox or Developer Tools for Chrome, end users are able to manipulate (add, alter, delete):
Your HTML
Your CSS
Your JS
Your HTTP headers (data packets sent to your server)
Cookies
To answer your question directly: if you are solely relying on JavaScript (and most likely cookies) to track user session state and deliver different content to members and guests, then I can say with absolute certainty that other people will circumvent your security, and it would be trivial to do so.
Designing secure applications is not easy, a constant battle, and takes years to fully master. Hacking applications is very easy, fun for the whole family, and can be learned on YouTube in 20 minutes.
Having said all that, hopefully the content you are containing in the JS is not "mission-critical" or "sensitive-data". If it is, I would seriously weigh the costs of hiring a third party developer who is well versed in security to come in and help you out. Because, like I said earlier, creating a truly secure site is not something easily done.
Short Answer: Yes.
Anything on the users computer can be viewed and changed by the user, and any user can write their own scripts to execute on the page.
For example, you will up vote this post automatically if you paste this in your address bar and hit enter from this page:
javascript: $('#answer-7061924 a.vote-up-off').click();
It's not really hacking because you are the end user running the script yourself, only doing actions the end user can normally do. If you allow the end user on your site to perform actions that affect your server in a way they shouldn't be able to, then you have a problem. For example, if I had a way to make that Javascript execute automatically instead of you having to run it yourself from your address bar. Everyone who came to this page would automatically upvote this answer which would be (obviously) undesired behavior.
Firebug and Greasemonkey can be used to replace any javascript: the nature of the Browser as a client is such that the user can basically have it do anything they want. Your specific scenario is definitely possible.
well, if your scripts are public and not protected by a server side than the Hacker can run it in a browser like mozilla.
you should always keep your protected content in a server side scripting and allow access by the session (or some other server side method)
Yes a user can edit scripts however all scripts are compiled on the user's machine meaning that anything they alter will only affect their machine and not any of your other visitors.
However, if you have paid content which you feed using a "members-only" script then it's safest if you use technology on the server to distribute your members-only content rather than rely on the client scripts to secure your content.
Most security problems occur when the client is allowed to interact with the server and modify data on the server.
Here's a good bit on information you can read about XSS: http://en.wikipedia.org/wiki/Cross-site_scripting
To put it very simply:
The web page is just an interface for clients to use your server. It can be altered in all possible ways and anyone can send any kind of data to your server.
For first, you have to check that the user sending that data to your server has privileges to do so. Usually done by checking against server session.
Then you have to check at your server end that you are only taking the data you want, and nothing more or less and that the data is valid by validating it on your server.
For example if there is a mandatory field in some form that user has to fill out, you have to check that the data is actually sent to server because user may just delete the field from the form and send it without.
Other example is that if you are trying to dynamically add data from the form to database, user may just add new field, like "admin", and set it to 1 and send the form. If you then have admin field in database, the user is set as an admin.
The one of the most important things is to remember avoid SQL injection.
There are many tools to use. They are made for web developers to test if their site is safe. Hackbar is one for example.
I am building a website for a customer who may not be very computer literate. This person knows how to use email. How can I build a website (purely html, javascript) where he can email his latest prices and the website automatically updates itself. I dont think he would be literate enough to FTP file some where. Is it possible?
How to build a secure login page and redirect to order page using only javascript and html?
How to create secure administrative section on javascript/html only website?
I would advise you to create a nice admin web interface, and teach him how to use it. Or, agree some kind of Excel format for product prices, and teach the steps of uploading a csv file. Doing things by email would complicate things in my opinion.
As in the website receives the email as data input? That's probably not going to work very well. Also, if the client is as you imply, expect those emails to be poorly formatted, filled with typos, etc. It's not a very good data entry medium by any means.
The ideal solution would be to build an admin page into the website where the client can enter the information in as controlled a manner as possible, validating the information on the spot rather than through an email (would the server send a reply email for invalid data? that would get infuriating quickly). A simple and intuitive UI should be able to overcome any computer literacy issues he may have.
I don't think this can be done purely in HTML/Javascript. It would need a server component. You would have to set up some sort of POP3 or IMAP listener that polls a mail server for correctly formatted email then dumps that into a database to update the site. Certainly not trivial.
I would build an administration portion of the site to allow the customer to log in and enter the data...no matter how illiterate, they certainly can be trained. ;-)
You could make the mail your prices thing work by just regulary checking a specific mailbox (over POP3 for example).
But that's something you won't be able to do in only pure html / javascript (and consider this: you would also need to store the mailbox credentials in client side code then!)
Email is a store-and-forward, asynchronous transport. You can use it to transport:
plain text (the body of an email)
styled text (the html body of a MIME email)
attached files
But none of those options will work well in your use case. You'd have to try to parse the body of the email if you were looking in the body for update information. -- Bad idea
And if you're using email to transport ordered data such as csv or Excel files, uploading the files directly to the website would enable a much better user interface.
You shouldn't use Excel files either since it will be too complicated for your user--he'd need to get the column (field) names exactly right, the content cells would also need to be exactly right, etc. Eg I use an excel file for input on one of my systems and a constant problem is zip/postal codes since they look like numbers but can have significant leading zeroes. Few users know how to enter them...
Recommendation create a set of web forms in the administrative section of the website. Your customer will be happy and you'll be even happier due to lower volume of support calls.
A lot of my visitors are blind (with it being a site for the blind), and often when trying to diagnose problems, I'd like to know what version of browser etc they're using, whether flash is installed. Because more often than not, someone will swear they are using X, when in fact Y is installed. Currently, I'm using http://jsbrwsniff.sourceforge.net/usage.html piped into an email, but I've got 2 problems here:
First of all, jsbrwsniff is quite "heavy" and hasn't been updated since early 2007, so there's a lot of -1's in the result.
Secondly, if I call it as follows, the page reloads:
Email feedback
And if I call it like this, the page goes blank and looks like it's trying to infinitely load a blank page:
Email feedback
See the nightmare for yourself here:
http://kingston.talking-newspapers.co.uk/
Now, I know there are 1001 articles and comments here and elsewhere saying "don't use browser sniffers, they can be spoofed (etc)", but honestly, you'll have to trust me that this is a significantly useful tool when you're talking someone in their more "senior years" and using a screenreader through "help > about", when they've clicked the wrong window to start with!
I'm using jquery anyway in the site, and I'm aware of $jQuery.browser and $jQuery.support, but these don't tell me the elements I need (like whether Flash is installed, and what version etc). I've looked everywhere for a jquery plugin for my needs, with no luck.
Finally, if I have to stick to the current method of jsbrwsniff then it's not the end of the world, but if anyone knows a way of launching the user's email client populated with the information I need but WITHOUT refreshing or blanking the page, I'd love to know.
BTW - there's a good reason for not using a webform, which is simply because it's easier for the screen-reader user to use an email client they are used to.
Thanks!
Tthat E-Mail should definitely be sent from the server side IMO.
You could make an Ajax request containing all the information you are sniffing to a PHP or other server side script. That script would receive the data and send the E-Mail. It's much more reliable that way.
Other than that, can you emphasize your exact question - is it the sniffing part, or the sending part...?
When the user want's to submit the browser details, you could dynamically create a form (e.g. in a hidden DIV) that contains all the deails you need and inoke the users email client by using a mailto: action URL. For details, see http://www.javascript-coder.com/javascript-form/javascript-email-form.phtml
But I'm not sure how to get the mail automatically sent. That would seem to transcend the security of the browser. So, your users will still have to click send.
Have you considered using mailto: to open the mail client and get the collected information into an email?
I'm not sure if your jquery can format the information you collected into a href link, but if so something like this may be what you're looking for:
mail
I'm working on a website for my county's fair. I want to allow my visitors to be able to ask me questions by inputing their name, email, and comment in a form like this one:
http://lincolnfair.net/images/feedback.JPG
So I guess my real question is how can I send an email (using JavaScript/JQuery) to myself with all these fields as the main body of the email.
You should use a server-side script (e.g. PHP, Python, Perl, etc.). With pure HTML and JavaScript, you can use a mailto form, but this will be very unreliable.
I will suggest uservoice.com , it can integrate with your site nicely, a much more powerful user feedback system, without spending time to code the feedback system yourself
As others have indicated, this is a typical task that can be solved easily using a server-side language. Javascript and jQuery aren't the right tool for this particular problem. To point you in the right direction, use method="post" for your form, and you can access users' submission in a PHP file by examining the $_POST variable. If a <input> element in your form has name="email" in your email, you can access that variable in PHP as $_POST['email']. If you're interested in a PHP solution, look at the documentation for the mail() function.
Jukka has a good guide on How to write HTML forms. It should give you everything you need to produce something functional.
You need a server side component, nothing client side will be a reasonable substitute for that. JavaScript won't help for a form as simple as the one you describe.
The most reliable way will be to use a server side script in your preferred language. The specifics of how to do this are probably outside the scope of this question and would depend upon your language of choice.
Your other option is to set the action of the form as a mailto: which will use the visitors preferred email client to send the email. This will work but is really bad and relies on the viewer having an email client installed and configured.
you can find out more information about the mailto option at http://www.chami.com/tips/internet/010597I.html
Another good option would be a third party site such as www.wufoo.com which handle all of the email business server side for you on their own servers. I believe Wufoo even allow you to embed their forms within your own site.
If you want it to be available on every page, you might want to consider using jQuery and the UI Dialog plugin. You could set it up so that the default feedback is a mailto which gets replaced using javascript with a link that brings up a jQuery Dialog containing the fields you want to collect. This could be submitted back to your server via AJAX and delivered to you via email from the server.
EDIT: Since you've edited your question to indicate a server-side only solution, the above seems somewhat out of context. With others, I would agree that using some client-side code to actually send the email is the way to go (as alluded to above). I think it's preferable to use your own server for this, but I'm sure that you can find many "form to email" services. I would avoid these, unless you want your email addresses harvested for use in SPAM. You might also be able to use a signed applet or ActiveX control for this, again I would not go down that route. As indicated above, I would let the browser handle the interface, but my server handle the sending of the email.
I am not sure i understand your question completely, but if all you want to do is conduct a survey over email, i don't think you need to use jQuery or HTML.
A very simple way to do it is to use the 'Forms' feature in Google Docs.
