Entry: JS_DeleteElement (Function)
Summary: Public. Removes a specified element or numeric property from an object.
Syntax:
JSBool JS_DeleteElement(JSContext *cx, JSObject *obj,
jsint index);
Argument Type Description
cx JSContext * Pointer to a JS context from which to derive runtime information.
obj JSObject * Object from which to delete an element.
index jsint Index number of the element to delete.
Description:
JS_DeleteElement removes a specified element or numeric property, index, from an object, obj. If an object references an element belonging to a prototype, the element reference is removed from the object, but the prototype's element is not deleted. If deletion is successful, JS_DeleteElement returns JS_TRUE. Otherwise it returns JS_FALSE.
For JavaScript 1.2 and earlier, if failure occurs because you attempt to delete a permanent or read-only element, JS_DeleteProperty reports the error before returning JS_FALSE. For JavaScript 1.3, the attempt is silently ignored.
