I have the following form on my page: <input id='startDate' type='datetime-local' step=1 name='startDate'> I use this code to get the value of the field: var start = $('#startDate').val(); My problem is that the value of the input field remains undefined until every part of it has been filled out, including hours, minutes, seconds, and AM/PM. I would like to be able to get a value from the form with as little as just the year selected. How can I go about doing this? I'm happy to zero out the values not filled out, but I can't figure out how to get the part of the datetime-local that the user

As you know, input component has an attribute, checked to whether mark the checkbox as enabled by default or not. <input type="checkbox" name="mycheckbox" checked="checked"/> To disable the checkbox by default, the checked exception should be declared. Is it possible to set checked attribute by a flag in Thymeleaf? According to the official thymeleaf documentation http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes th:checked is considered as a fixed-value Boolean attribute. <input type="checkbox" name="active" th:checked="${user.active}" /> Where user

I'm working on building new site, and I need a drop down menu to select the amount of something in my site. But at the same time I need this drop down list to accept text. So if the client wants to choose from the drop down list then he can, also if the client want to enter the amount by text then he can also. As you can see I want to make it dual. For example: suppose there is an amount drop down menu, and its elements are (1,2,3); Suppose now that the client needs the amount to be 5 - this is his right - it does not exist in the drop down list, so the client now must enter the amount

The default maximum length for a HTML input ( <input type="text"> ) is 524288 characters. That seems like a very peculiar number, why was it chosen? Patrick Hofman According to the w3c the maximum value is unlimited: maxlength = number [CN] When the type attribute has the value "text" or "password", this attribute specifies the maximum number of characters the user may enter. This number may exceed the specified size, in which case the user agent should offer a scrolling mechanism. The default value for this attribute is an unlimited number. Despite that, I have noticed that in Chrome indeed

I need to have users enter floating point numbers, so I use the following element: <input type="number" name="my_number" placeholder="Enter number"/> Works great on Firefox, but Chrome complains that the number is not an integer when I try to enter a decimal. That's a problem for my case. If I enter a step attribute, then Chrome allows the floating point number: <input type="number" name="my_number" placeholder="Enter number" step="0.1"/> But then the problem is 0.15 can't be entered... The step doesn't appear to suit my needs. The W3C spec mentions floating-point numbers throughout the

My objective is to observe an input value and trigger a handler when its value gets changed programmatically . I only need it for modern browsers. I have tried many combinations using defineProperty and this is my latest iteration: var myInput=document.getElementById("myInput"); Object.defineProperty(myInput,"value",{ get:function(){ return this.getAttribute("value"); }, set:function(val){ console.log("set"); // handle value change here this.setAttribute("value",val); } }); myInput.value="new value"; // should trigger console.log and handler This seems to do what I expect, but it feels like a
