show input fields instead of text when you click an "edit" link

Question

I am currently creating a backend. What I need is some jquery to insert some different form fields. I can for example have this code:

<div>
    <div>
        Name
    </div>
    <div>
        Type
    </div>
    <div>
        <a class="edit" href="#">Edit</a>
    </div>
</div>

This code needs to get converted so the Name and Type text is insted the values of two input fields when I click a.edit

EDIT:

I've tried this code - but when I click "a.ff-save" it does not alert??? What is my problem?

<script type="text/javascript">
$(document).ready( function() {
    var this_form_id = $("input#form_id").val();
    $("#formfield-list div.formfield-ff:odd").css('background', '#f6f6f6');


    $("a.ff_add").click( function() {
        var name_val = $("input#new_field_name").val();
        var type_val = $("input#new_field_type").val();
        var demand_val = $("input#new_field_demand").val();
        $.ajax({
            type: "POST",
            url: "{pref_folder}/admix/forms/addFormField",
            data: ({ form_id: this_form_id, field_name: name_val, field_type: type_val, field_demand: demand_val }),
            success: function(text) {

                $.ajax({
                    type: "post",
                    url: "{pref_folder}/admix/forms/getFormFields",
                    data: { form_id: this_form_id },
                    success: function(t) {
                        $("#formfield-list").empty().append(t);
                        $("#formfield-list div.formfield-ff:odd").css('background', '#f6f6f6');
                    },
                    dataType: "html"
                });


                $(".add-succes-message").empty().append('<div class="msg">'+text+'</div>');
                $(".add-field-row").slideUp(500, function(){
                    $(".add-field-row").slideDown(500);
                }).delay(3500);
                $(".add-succes-message").slideDown(500, function(){
                    $(".add-succes-message").slideUp(500);
                }).delay(3500);

            },
            cache: false,
            async: false,
            dataType: "html"
        });
    });

    $("a.ff-save").click(function (){
        alert("ok");
    });

    $("a.ff-edit").click(function (){
        var fid = $(this).prev().val();

        var nameValue = $("#ff-"+fid+" div.ff-name").html().trim();
        var typeValue = $("#ff-"+fid+" div.ff-type").html().trim();
        var demandValue = $("#ff-"+fid+" div.ff-demand").html().trim();
        var typeInt;

        if( typeValue == "Tekstfelt, 1 linje" )
        {
            typeInt = 1;
        } else {
            typeInt = 0;
        }


        $("#ff-"+fid+" div.ff-name").html('<input type="text" name="name" class="jq-input" value="'+nameValue+'" />');
        $("#ff-"+fid+" div.ff-type").html('<input type="text" name="type" class="jq-input" value="'+typeInt+'" />');
        if( demandValue == "Ja")
        {
            $("#ff-"+fid+" div.ff-demand").html('<input type="checkbox" name="demand" class="jq-input" value="" checked="checked" />');
        } else {
            $("#ff-"+fid+" div.ff-demand").html('<input type="checkbox" name="demand" class="jq-input" value="" />');
        }

        $("#ff-"+fid+" .ff-edit, #ff-"+fid+".ff-delete").hide();
        $("#ff-"+fid+" div:last").html('<a href="#" class="ff-save">Save</a>');
    });

    $("a.ff-delete").click();
});
</script>

Answer 1

I tried a few different approaches and this is what I came up with:

HTML:

<span class="subject">
    <span class="text"> subject </span>
    <input class="input" type="text" name="subject" val="subject" hidden/>
</span>

Jquery:

function showInput(){
    $(this).off('click');
    $(this).siblings('input').each(function(){$(this).show();});
    $(this).siblings('input').focus();
    $(this).hide();
}
function hideInput(){
    $(this).hide();
    $(this).siblings('span').show();
    $(this).siblings('span').click(showInput);
}
$(function(){
    $('.text').click(showInput);
    $('.input').blur(hideInput);
}

Simply put when you click on the given text it will turn into an input box and when the input box loses focus then it turns back into regular text.

I also made the show/hide functions separate callable functions so I could reset the click listener within the hideInput function.

Check this jQuery plugin. It exactly does what you are looking for.

JEditable

If you are not inclined towards using the plugin, then try the code below:

<div>
    <div>
        <label class="editable">Name</label>
        <input class="editable" type="text" name="name" style="display:none"/>
    </div>
    <div>
        <label class="editable">Type</label>
        <input class="editable" type="text" name="type" style="display:none"/>
    </div>
    <div>
        <a class="edit" href="#">Edit</a>
    </div>
</div> 
<script type="text/javascript">
    $(function(){
        $(".edit").click(function(){
            var $this = $(this);
            var text = $this.text();
            if(text=="Edit"){
                $this.text("Cancel");
            }
                        else{
                             $this.text("Edit");
                        }
            $(".editable").toggle();
        });

        $("input.editable").change(function(){
            $(this).prev().text($(this).text());

        });
    });
</script>

EDIT:

To bind the click event handler to the anchor element use the live function of jQuery. e.g:

$("a.ff-save").live("click", function (){         
 alert("ok");     
});

Answer 3

I did something like this at work, here was my solution:

HTML

<div id='container'>
    <div id='name' class='text'>
        Name
    </div>
    <div id='type' class='text'>
        Type
    </div>
    <div>
        <a class="edit" href="#">Edit</a>
    </div>
</div>

JQuery

function StartEditState() {
    var container = $('#container');
    container.find('a.edit').unbind('click').click(SaveEditState).html('Save'); //this changes edit button save button
    container.find('div.text').each(function() {
        $(this).html('<input class="new_val" type="text" value="' + $(this).html() + '" /><input class="orig_val" type="hidden" value="' + $(this).html() + '" />'); // this creates a hidden with the old value and an input that they can change
    });
    return false;
}

To save the values you just need to do this $('#name input.new_val').val() (for name, use #type for type) or to return to the original values use $('#name input.orig_val').val()

Hope you like it.
