阅读更多关于 How to set the value of a text input with MooTools

问题 I have just begun playing with MooTools, and I don't understand why the following happens: var input = new Element('input'); input.set('type','text'); input.set('value','this is the value'); console.log(input); results in: <input type="text"> , so setting the value hasn't worked. But if I do this: var input = new Element('input'); input.set('type','text'); input.set('someValue','this is the value'); console.log(input); I get the expected result of <input type="text" somevalue="this is the

阅读更多关于 Using file input element in hta file prevents deleting selected file

问题 If an input html element of type=file is used to select a file then that file cannot be deleted by the hta program.

阅读更多关于 Inspect HTML5 date picker shadow DOM

问题 I'm trying to inspect the shadow DOM for certain HTML5 controls, like the date picker for the input type="date" and the actual suggestion dropdown list for inputs bound to a datalist . Preferably in Chrome, but other browsers will do too.
