React ignores 'for' attribute of the label element

In React (Facebook's framework), I need to render a label element bound to a text input using the standard for attribute.

e.g. the following JSX is used:

<label for="test">Test</label>
<input type="text" id="test" />

However, this produces HTML missing the required (and standard) for attribute:

<label>Test</label>
<input type="text" id="test">

What am I doing wrong?

just using react htmlFor to replace for!

Since for is a reserved keyword in JavaScript, React elements use htmlFor instead.

refs

you can find more info by following the below links.

Yes, for react,

for becomes htmlFor

class becomes className

etc.

see full list of how HTML attributes are changed here:

both for and class are reserved words in JavaScript this is why when it comes to HTML attributes in JSX you need to use something else, React team decided to use htmlFor and className respectively

For React you must use it's per-define keywords to define html attributes.

class -> className

is used and

for -> htmlFor

is used, as react is case sensitive make sure you must follow small and capital as required.

The for attribute is called htmlFor for consistency with the DOM property API. If you're using the development build of React, you should have seen a warning in your console about this.
