将表单转换为纯文本

Question

I have a page that generates forms depending on user choice. I want to know if there is a way to convert the form into plain text? Ex. The form has 4 fields, each has a label. I would like to take all the labels/fields and print them to the user as follows:

label1 field1
label2 field2
label3 field3
label4 field4

Is there a way to do so?

You can use jQuery to generate basic output, for example:

var texts = [];
$("form label").each(function() {
    var oLabel = $(this);
    var oInput = oLabel.next();
    texts.push(oLabel.text() + " - " + oInput.val());
});
var plainText = texts.join("<br />");
$("#Output").html(plainText);

This will iterate over all the form labels, then take the next element of each label which is the input.

If you don't mind an extra file, with PHP.

You'd need to make a small php file to echo all the form information like this:

<?php
$label1 = "label1";
$label2 = "label2"; //Set all labels here
$label3 = "label3";
$label4 = "label4";
echo $label1 . " " . $_POST['field1'] . "<br />"; //Change to get depending on your method.
echo $label2 . " " . $_POST['field2'] . "<br />";
echo $label3 . " " . $_POST['field3'] . "<br />";
echo $label4 . " " . $_POST['field4'] . "<br />";
echo "Done.";
?>

and put that in it's own file. Set the form's action attribute to that file and it will print out all the data.

One method, without a JavaSCript library, is:

var form = document.getElementsByTagName('form')[0];

form.onsubmit = function(){

    var labels = document.getElementsByTagName('label');

    if (!document.getElementById('container')){
        var container = document.createElement('ol');
        container.id = 'container';
    }
    else {
        var container = document.getElementById('container');
        while (container.firstChild){
            container.removeChild(container.firstChild);
        }
    }

    for (var i=0,len=labels.length; i<len; i++){
        if(document.getElementById(labels[i].getAttribute('for'))){
            var newLi = document.createElement('li');
            var iText = document.createElement('span');
            newLi.innerHTML = labels[i].innerHTML;
            iText.innerHTML = document.getElementById(labels[i].getAttribute('for')).value;
            newLi.appendChild(iText);
            container.appendChild(newLi);
        }
    }

    document.getElementsByTagName('body')[0].appendChild(container);

    return false;

};

You may get the value for labels and fields in javascript using

var label1 = getElementById("id").name

Create a string formatted as you want to show the user and show all the values with

document.write(string);
