Select element and jQuery CHANGE event in IE8?

由 扶醉桌前 提交于 2019-12-10 17:33:50
问题 I have a small script on my site that calculates a price quote based on the options chosen in 4 different Select elements. The price quote is written into a div and is updated each time there is any change in the selected options.

In what authorative specification is the onChange event exhaustively defined?

问题 I was slightly surprised to find out that the onChange event in an html document is fired on a text input or textarea not at the very moment when its value actually changes, but only when focus leaves the element (if its value has changed, of course). So I was looking for the specification that states that, and I can't find it. I can find millions of tutorials explaining that, including W3Schools' ones, but I can't find the standard that defines when the event is expected to be fired. In the

Why is onchange on a checkbox not fired when the checkbox is changed indirectly

由 痞子三分冷 提交于 2019-12-10 14:56:12
问题 I'm using Prototype to monitor checkboxes, so I can add javascript checks to them. When the tr or td in which the checkbox is located is clicked, the checkbox should be checked. When you click directly on a checkbox, the onchange event is fired, so you'll get an alert. When the checkbox' value is changed by javascript (when you click on the tr or td), onchange is not fired. Why is onchange not fired when the checkbox is changed indirectly? This is the javascript I'm using. Element.observe
