uniqueID Chapter 1 ✦ Generic HTML Element Objects (Chapter 15) NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ ✓ Example Listing 15-18 demonstrates the recommended syntax for obtaining and applying a browser-generated identifier for an object. After you enter some text into the text box and click the button, the addRow() function appends a row to the table. The left column displays the identifier generated via the table row object’s uniqueID property. IE5+ generates identifiers in the format “ms__idn”, where n is an integer starting with zero for the current browser session. Because the addRow() function assigns uniqueID values to the row and the cells in each row, the integer for each row is three greater than the previous one. There is no guarantee that future generations of the browser will follow this format, so do not rely on the format or sequence in your scripts. Listing 15-18: Using the uniqueID Property Inserting an IE5+/Windows Table Row function addRow(item1) { if (item1) { // assign long reference to shorter var name var theTable = document.all.myTable // append new row to the end of the table var newRow = theTable.insertRow(theTable.rows.length) // give the row its own ID newRow.id = newRow.uniqueID // declare cell variable var newCell // an inserted row has no cells, so insert the cells newCell = newRow.insertCell(0) // give this cell its own id newCell.id = newCell.uniqueID // display the row’s id as the cell text newCell.innerText = newRow.id newCell.bgColor = “yellow” // reuse cell var for second cell insertion newCell = newRow.insertCell(1) newCell.id = newCell.uniqueID Continued 49 elementObject.uniqueID

Its purpose is to turn the color style property of an object to either a elementObject.addBehavior()
