input type=“text” vs input type=“search” in HTML5

问题:

I'm new to HTML5 as begun to work with HTML5's new form input fields. When I'm working with form input fields, especially <input type="text" /> and <input type="search" /> IMO there wasn't any difference in all major browser including Safari, Chrome, Firefox and Opera. And the search field also behaves like a regular text field.

So, what is the difference between input type="text" and input type="search" in HTML5?

What is the real purpose of <input type="search" />?

回答1:

Right now, there isn't a huge deal between them - maybe there never will be. However, the point is to give the browser-makers the ability to do something special with it, if they want.

Think about <input type="number"> on cellphones, bringing up number pads, or type="email" bringing up a special version of the keyboard, with @ and .com and the rest available.

On a cellphone, search could bring up an internal search applet, if they wanted.

On the other side, it helps current devs with css.

input[type=search]:after { content : url("magnifying-glass.gif"); }

回答2:

It does absolutely nothing in most browsers. It just behaves like a text input. This isn't a problem. The spec doesn't require it to do anything special. WebKit browsers do treat it a bit differently though, primarily with styling.

A search input in WebKit by default has an inset border, rounded corners, and strict typographic control.

Also,

This isn't documented anywhere that I know of nor is it in the spec, but you if you add a results parameter on the input, WebKit will apply a little magnifying glass with a dropdown arrow showing previous results.

<input type=search results=5 name=s>

Reference

Above all, it provides a semantic meaning to the input type.

Update:

Chrome 51 removed support for the results attribute:

回答3:

Visually/functionally, 2 differences if the input type is 'search':-

1. You get a 'X' symbol at the end of the input/search box to clear texts in the box
2. Pressing 'Esc' key on keyboard also clears texts

回答4:

On some browsers, it also supports the "results" and "autosave" attributes which provides automatic "recent searches" functionality with the magnifier icon.

回答5:

Actually be very careful about assuming it does nothing. When you go to style inputs with the type search they have certain attributes that cannot be changed. Try to change the border on one and you will find it quite impossible. There are several other disallowed CSS attributes, check out this for all the details.

Also as mentioned by Jashwant there's the result attribute, though it doesn't work very well unless you also include the autosave attribute. The drop down will not work in most browsers, however, so use at your own peril.

回答6:

There's browser difference in action, when you type some words then keyed ESC in input type="search" in chrome/safari the input box will get cleared. but in type="text" scenario, the words will not get cleared. So be careful choosing the type especially when u use it for autocomplete or search related feature

回答7:

Bonus point: input type="search" has the ability to use the onsearch attribute (although I have noticed this does NOT work in Microsofts new Edge Browser), which eliminates the need to write a custom onkeypress=if(key=13) { function() } thing.

回答8:

using input type="search" make the keybord enterkey's text show "search", which may improve user experience. however, you have to adjust the style if using this type.

回答9:

The majority of functionalities are the same but 1 difference we can see using browsers is that search input is a little different in SAFARI and CHROME. They add "x" icon at the right side, but it's the same thing for FireFox, IE, etc.

In short, no difference for Firefox, IE, Opera, only for safari and chrome.

回答10:

It depends on the programmers point of view, a programmer can easily determine the purpose of the input by looking on the type and it's easy for CSS styling and for JavaScript or JQuery to verify rule in the inputs.

回答11:

But it has a bad affect on yout input element, if you set

<input type="search">

And in your css you set

input {background: url("images/search_bg.gif");}

It wont showup at all.
