forms

问题 So I have been looking online for several hours for what I think is a very simple answer but I can't seem to find it. I am trying to understand how PDF form data submitting works. My goal is to read form data submitted from a PDF form that I set up into my PHP script. I want my PHP script to parse the form data and plug it into my SQL database. The roadblock I am running into is how do I receive the file so I can parse it? What is the filename of the file that gets submitted? I have my submit

问题 I'm using Prestashop as my ecommerce shopping cart and CMS solution and was having problems receiving emails sent via the contact form. I asked around and found the problem to be due to the fact that I need to assign the 'from' address as something from my domain (e.g. do_not_reply@mydomain.com) and the email entered by user to be assigned a different variable (e.g. 'replyemail'). However, the Prestashop contact form is created with a PHP Smarty template engine, which has separate contact

问题 I have a page. The user submits the page and sends it to a PHP results page. It works fine. Now, I want the results page to link to another page, and for the elements on that page to depend on what was on the results page. I know how to pass form variables to another page, but I don't know anything about passing non-form variables. From my searching on the web, my best guess is that I should be passing by URL. Is this correct? If so, a possible problem: the page I want the results page to

问题 I am creating an order form, using HTML, where I need to add a dropdown menu for 'which color' and a corresponding input field, which will be read-only, for the 'amount'. Creating the order form is easy but now what I want is that I want the 'amount' value to change depending on which 'color' has been selected from the 'which color' dropdown menu. Lets say that we've five options inside the 'which color' dropdown menu, namely: Black White Blue Green Orange <select id="color"> <option value=

问题 I am trying to post json data to an URL which I have no control. The API document says only json data is accepted. I am thinking whether I can use html form to make it easier. There are lots of posts here in regards of how to "post json data using form", none of them applies my situation. The problem is, as far as I know, if you post data using form, the thing being post is always "name=value", however, the API wants only "value". That is to say, even though I can JSON.stringify input values

问题 I have a form in an iframe and submit it. How can I tell when the submission completes? I'm using jQuery to submit the form but don't think there's a callback: $("#myForm").submit(); // how to attach event to submission complete? 回答1: Submission of the form will redirect you to the next page. But you can always try the ajax function http://api.jquery.com/jQuery.ajax/ Adding callback is as easy as $.ajax({ url: "page.php", success: function() { doWhateverYouWant(); } }); 回答2: If you submit a

问题 The title seems easy, but I need help. I have a form with a field input "email" of which value is null until the user fills it up. Okay, on click of the submit button, I call the function validate() which is: function validate(){ var email=document.getElementById("email"); if(!(/[\w-\.]{3,15}@([\w-]{2,}\.)*([\w-]{2,}\.)[\w-]{2,4}/.test(email))) { email.setAttribute('value','Insert a correct email'); email.style.border="2px solid red"; } else { alert("Valid field"); // This is to test it works

问题 I know there are multiple ways to select a particular option from a using jQuery: $select.val("someValue") $option.attr("selected", "selected") $select[0].selectedIndex = 1 Assuming you have both the index of the option you wish to be selected and its value, what's the most correct way (from the above, or otherwise) to make it selected? By "most correct", I mean: Best practice, if any Will correctly set the value so that it is submitted with the form, and can be retrieved using any of the

问题 I have a massive form with more or less 80 / 90 inputs. My main problem is How can I pass all those inputs belonging to unique form in an ajax request without map the inputs manually into a object? I know that with jquery you can use serialize() function selecting the form. Is there any helper function in angular to achieve that?
