Chapter 1 ✦ Generic HTML Element Objects (Chapter 15) Example Use The Evaluator (Chapter 13 in the JavaScript Bible) to experiment with both the contentEditable and isContentEditable properties on the myP and nested myEM elements (reload the page to start with a known version). Check the current setting for the myEM element by typing the following statement into the top text field: myEM.isContentEditable This value is false because no element upward in the element containment hierarchy is set to be editable yet. Next, turn on editing for the surrounding myP element: myP.contentEditable = true At this point, the entire myP element is editable because its child element is set, by default, to inherit the edit state of its parent. Prove it by entering the following statement into the top text box: myEM.isContentEditable While the myEM element is shown to be editable, no change has accrued to its contentEditable property: myEM.contentEditable This property value remains the default inherit. You can see an additional example of these two properties in use in Listing 15-7. isDisabled NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ Example Use The Evaluator (Chapter 13 in the JavaScript Bible) to experiment with both the disabled and isDisabled properties on the myP and nested myEM elements (reload the page to start with a known version). Check the current setting for the myEM element by typing the following statement into the top text field: myEM.isDisabled This value is false because no element upward in the element containment hierarchy is set for disabling yet. Next, disable the surrounding myP element: myP.disabled = true At this point, the entire myP element (including its children) is disabled. Prove it by entering the following statement into the top text box: myEM.isDisabled 27 elementObject.isDisabled
28 JavaScript Examples Bible: The Essential Companion to JavaScript Bible While the myEM element is shown as disabled, no change has accrued to its disabled property: myEM.disabled This property value remains the default false. isMultiLine NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ Example Use The Evaluator (Chapter 13 in the JavaScript Bible) to read the isMultiLine property for elements on that page. Try the following statements in the top text box: document.body.isMultiLine document.forms[0].input.isMultiLine myP.isMultiLine myEM.isMultiLine All but the text field form control report that they are capable of occupying multiple lines. isTextEdit NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ ✓ ✓ Example Good coding practice dictates that your script check for this property before invoking the createTextRange() method on any object. A typical implementation is as follows: if (document.all.myObject.isTextEdit) { var myRange = document.all.myObject.createTextRange() [more statements that act on myRange] } lang elementObject.lang NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ ✓ ✓ ✓
