This way, that line will only run when the function is called. Move that line inside the function, and it should work. Thus, document.getElementById('lolz') will return null, and document.getElementById('lolz').value should cause an error. line is evaluated before the browser knows about the existance of an input with id lolz.

Your code is parsed line by line, and the lol =. Is before the actual element on your markup:

This specification includes examples that illustrate how to avoid using deprecated elements. Deprecated elements may become obsolete in future versions of HTML. Its value is an identifier for the language, but since these identifiers are not standard, this attribute has been deprecated in favor of type.Ī deprecated element or attribute is one that has been outdated by newer constructs. This attribute specifies the scripting language of the contents of this element. See W3 HTML4 Specification, the SCRIPT element:ĭeprecated. Note that the script element must follow the input element it refers to, because elements are only queryable with getElementById if they already have been parsed and created.Įdit: I removed the language='javascript' attribute, because it's deprecated. Var lol = document.getElementById('lolz')

- Defines an independent, self-contained content.

- Defines a section in a document.

- Defines a set of navigation links. If you insist var lol to be set outside the function kk, then I propose this solution: HTML has several semantic elements that define the different parts of a web page:

- Defines a header for a document or a section.

Var lol = document.getElementById('lolz').value You can inadvertently overwrite important data in this way. Even if this could work, it's bad programming style. click() to bind kk's onclick handler, instead of doing that inline in the HTML.ĭo not use global variables in this way. The function will be run as soon as the DOM is ready. This can be done with 'plain' JavaScript, but it's much easier to use a DOM library like jQuery.

The other option is to wait until the DOM is ready (which is usually much earlier than onload). There is, however, a problem with onload: it waits until everything (including images, etc.) is loaded. (On a side note: the language attribute of the tag is deprecated. One is to wait until the entire document is loaded, like this: You've already found the most obvious solution: by calling getElementById inside the function, the DOM will be loaded and ready by the time the function is called, and the element will be found like you expect it to. Because of that, getElementById will return null ( see MDN). The reason you function doesn't work when lol is defined outside it, is because the DOM isn't loaded yet when the JavaScript is first run.
