To remove the disabled prop, you should set its value to false. This needs to be the boolean value for false, not the string ‘false’. So, if the value for validated is either a 1 or a 0, then conditionally set the disabled prop based off that value. E.g.: <input type=”text” :disabled=”validated == 1″> Here … Read more
Use the min attribute like this: <input type=”number” min=”0″>
And you can add a max attribute that will specify the highest possible number that you may insert <input type=”number” max=”999″ /> if you add both a max and a min value you can specify the range of allowed values: <input type=”number” min=”1″ max=”999″ /> The above will still not stop a user from manually … Read more
The <label> tag allows you to click on the label, and it will be treated like clicking on the associated input element. There are two ways to create this association: One way is to wrap the label element around the input element: <label>Input here: <input type=”text” name=”theinput” id=’theinput’> </label> The other way is to use … Read more
If you want to disable client side validation for a form in HTML5 add a novalidate attribute to the form element. Ex: <form method=”post” action=”/foo” novalidate>…</form> See https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate

Unfortunately, HTML5 doesn’t provide a way of specifying ‘today’ in the HTMLInputElement.prototype.value. One must instead explicitly provide a RFC3339 formatted date (YYYY-MM-DD). For example: element.value = “2011-09-29”
This is one way of doing it: document.getElementById(“nameofid”).value = “My value”;
To read user input you can try the cmd module for easily creating a mini-command line interpreter (with help texts and autocompletion) and raw_input (input for Python 3+) for reading a line of text from the user. text = raw_input(“prompt”) # Python 2 text = input(“prompt”) # Python 3 Command line inputs are in sys.argv. … Read more
Well this is embarrassing… I found the solution I was looking for and it couldn’t be simpler. I used the following code to get the desired result. <label for=”fileSelect”>Spreadsheet</label> <input id=”fileSelect” type=”file” accept=”.csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel” /> Valid Accept Types: For CSV files (.csv), use: <input type=”file” accept=”.csv” /> For Excel Files 97-2003 (.xls), use: <input … Read more
The simplest way to accomplish this is to put the input method in a while loop. Use continue when you get bad input, and break out of the loop when you’re satisfied. When Your Input Might Raise an Exception Use try and except to detect when the user enters data that can’t be parsed. while … Read more
