    When typing in html forms, browsers like firefox or ie store the values, sometimes quietly. So when typing in another webforms, the browser smartly suggest the same information.

    javascript html-form onsubmit
    I’m asking this because I am at a complete loss myself and need a fresh pair of eyes.The following JavaScript function is successfully called on submission of the connected HTML form. The function starts and the first two if statements run (and halt the submission if they return false).Then, the first test alert “before” appears and then the form submits, completely missing out the rest of the function. While testing I changed the final line to return false so that whatever happen the function s

    Problem Statement:I have a DOM structure in which there are two forms objects present under different parents. The form objects share the same ID. Each form object has two elements in it with different values.Base Page:ParentA (id=ParentA) –> FormA (id=FormA) –> RadioOne (id=RadioOne) value=false, RadioTwo doesn’t exist.Popup:ParentB (id=ParentB) –> FormA (id=FormA) –> RadioTwo (id=RadioTwo) value=true, RadioOne doesn’t exist.The reason for structure is because the ParentB is a popup which

    I have a simple form with one input field. It works fine when I use the submit but hitting enter in the text field reloads the page with the form variable in the URL.I looked through the many solutions available online (except for JQuery since it seems like overkill for something this simple) and haven’t been able to get ‘enter’ to work. Any help would be great<form name=”myform” action=”” method=”GET” > Enter text: <br><input type=”text” name=”queryinput” onkeyup=”if(isEnterPress

    See example here. Clicking [Email Me] in the President’s header should open up the contact form with Webmaster selected from the dropdown, but that’s not happening.I know it should be trivial, but it’s not turning out that way. get stuff in email() is working alright but when it gets to the selecting an option, the code craps out. All relevant code is below.My HTML:<form method=”get”><select name=”to” id=”to-field”><option name=”President” value=”President”>President</option

    html-form undefined-index file-upload
    I have been developing an application that allows a user to upload files to the server. I had working forms until recently, when suddenly they stopped working. All the forms that do not work any more are the forms that have the enctype=’multipart/form-data’. But the other forms that do not have this works perfectly. I’ve checked the spelling, and I checked everything. It generates undefined indexes which really annoys me because it worked before. How can I resolve this?<form method=”post” enc

    EDIT:Ok so I’m updating this question, to show what I’ve built as I’ve still not been able to fix this issue. Here is an image of what I’ve got. So as you can see, When the user enters a value, the calculation (they are just percentage and total calculations are done “onkeyup”. As you can see because of this they return “NaN”. Is there a way for me to stop the field displaying a NaN and then subsequently only showing the total values?I have thought about this and I could just get all the fields
