Dynamic HTML: The Definitive Reference

Name

readyState — NN n/a IE 4 DOM n/a

Synopsis

Read-only

Returns the current download status of the script being loaded from an external library (.js) file. This property provides a more granular way of testing whether a particular downloadable element is ready to be run or scripted instead of the onLoad event handler for the entire document. As the value of this property changes during loading, the system fires an onReadyStateChange event.

Example

if (document.all.myExternalScript.readyState == "uninitialized") {
    statements for alternate handling
}

Value

One of the following values (as strings): complete | interactive | loading | uninitialized. Some elements may allow the user to interact with partial content, in which case the property may return interactive until all loading has completed.

Default

None.
