javascript dom manipulation

Every day a JS small demo form sort. Key points of knowledge: form manipulation in the DOM, node manipulation

HTML CREATE TABLE:Instead, the DOM is created by:window.onload=function() { var table=document.createelement (' table '); Table.width=300; Table.border=1;}Use the AppendChild () method to add a table's THEAD, tr,th. Such as:var thead=document.createelement (' thead '); Table.appendchild (thead);As you can see, creating tables using the DOM is tiring.Here's a look at how to get tabular data using th

elementElement.srcThe above method can be found to get some object properties and can be implemented using DOM Core or html_dom implementation, compared to the html_dom implementation is relatively short, but it can only be used to work with Web documents.3.css_domCss_dom is a CSS-based operation, in JavaScript in China, the main function of Css_dom technology is to get and set the various properties of th

listener for each child node.at the same time, this avoids the creation of memory that cannot be reclaimed. Even if you register an event with prototype observe and call stopobserving before deleting a node, you will generate a small amount of memory that cannot be reclaimed, so you should register the event listener for DOM nodes as little as possible .So, when it comes to registering events in the loop, it's time for us to consider the event mechan

them as a component, as we see in the process that two different components are bound to be regenerated, even if their content is very similar. The second revelation is that if you use a similar list to present elements, then the elements can be combined with key as much as possible, thus greatly improving efficiency and avoiding unnecessary performance losses.
