Accessing an array of HTML input text boxes using jQuery or plain Javascript?

First of all id attribute cannot contains or character There is lots of ways to get jQuery/plain JavaScript references to these elements. You can use descendant selector: fieldset id="list-of-fields"> $("#list-of-fields input"); document. GetElementById("list....").

GetElementsByTagName("input") You can also use attribute selector: $("inputname^=field") I'm not sure whether that's the only way but I think in plain JavaScript you'll have to fetch all input elements ( document. GetElementsByTagName ) and then loop through array of these elements and check each element (whether it has name attribute which value starts with field ).

Give each element a class and access the group using jQuery: Field 1: Field 2: jQuery: $("input. Fields"). Each(function (index) { // Your code here }); This will run the anonymous function on each input element with a classname of "fields", with the this keyword pointing to the current element.

See api.jquery.com/each/ for more info.

That's interesting. So the name field can include s but the ID can't. So at least from a PHP point of view, I'd still be able to treat the $_POST'field' data as an array?

And using $("inputname=field1").val() I can still access the value using jQuery. So the key is to use name and not depend on ID. – greggannicott Feb 3 '10 at 13:46 @greggannicott: Square brackets are permitted in name attributes but not in ID attributes.

I think the correct way to use it for PHP is just have name="field" for each and not name="fieldn" but I could be mistaken and both might work. – Andy E Feb 3 '10 at 13:51.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
