In HTML5, a form can define an attribute required to trigger the default checksum mechanism, such as:type= "text"/>The error message that pops up defaults to English.If you want to customize the language hint, you can:type= "text" required oninvalid= "invalidmsg (this);" />The JS method is:function invalidmsg (textbox) { if (textbox.value = = ') { textbox.setcustomvalidity (' cannot be empty '); } Else if (textbox.validity.typeMismatch) { textbox.setcustomvalidity (' Ple

This is a tough beat, and the Code previously written is no longer valid. Jquery checks whether the checkbox is selected. I wrote it like this at the beginning, and it's okay. $ ("# Ziduana"). attr ("checked") = "checked" Then it became invalid, I tried later. $ ("Ziduana"). attr ("checked") = true, $ ("# ziduana"). is (": checked ") In fact, these three judgment methods are acceptable, and I have tested them, but they always fail several times

Otherwise, FALSE is returned.Design ProcessFirst, design the webpage. Then, create a form and submit the file to be judged through the file field. Then, obtain the file path submitted in the form, and use the filectime () and filemtime () functions to detect the submitted file. Finally, the detection result is output.The key code of the index. php file is as foll

Javascript cannot directly use or determine whether two arrays are equal, whether they are equal or full. To determine whether the two arrays in JS are the same, you must first convert the arrays into strings and then compare them. JS needs to compare whether two arrays have the same elements, that is, all elements in the two arrays are the same, but the order of elements is not necessarily the same. You only need to sort the array first, and then compare whether the two arrays are equal.
