reading data from HTML page

[hsn]

hey everyone

i am currntly working on a project. for a function that i want to create there are too many methods to solve it. one of these methods that i am thinking of is to write a javascript function to read an HTML webpage, then to go to a text field next to (for example First Name label). the function should check the data in the text field if it is not correct it should correct it and then press the submit button at the end of the HTML webpage.

could this function be done? at what functions i could use to do it??

thanks for reading my question

Are not you asking for JavaScript Validation?

Is this HTML page the current page? If not, is it from the same domain?

From what you've described, it does look like form validation.

You can loop over input form elements on a page with document.getEle mentsByTagName( "input"). This will give you an array of input elements which you can loop over using a for loop.

If you want to read the whole body, document.body,i nnerHTML (or some DOM methods) would give you the content of the whole body.

I'm not sure what you mean by correcting. How would you know how to correct, e.g. if the first name hasn't been filled in, what are you going to put in its place?

what i mean by correcting... the text field should be fi
lled with an IP address of something. in the code the IP is predefined. so if the ip is wrong then change it to the correct one.
after that i have to press the save button on the page.
you have to know that the page is not my page. so i don't know the names of the fields and i don't know how to press the save button at the end of the page

thanks for helpping me

If it's not your page, how are you going to add the code? Using Greasemonkey?

If you know which field number it is, then getting the field value should not be a problem. Say it's the first field, then

var field = document.getElementsByTagName("input")[0];
var value = field.value;

will give you the field and value.

To click a button, use the button's click() method.
