Jquery:创建多个实体

我正在为 iPhone 网站创建一个便签提醒应用程序。目标是让用户创建尽可能多的“便签”——所有数据都将保存在本地存储中。

我这里有一个即时贴的工作原型:

    $( function() {
        $('#sticky-edit').bind( 'taphold', function( e ) {
            alert( 'You tapped and held!' );
            var thetext = localStorage.getItem("sticky");
            $(".sticky-text").html('<input id="sticky-input" type="text" value="'+thetext+'" />');
      } ); 
      
        $('#sticky-submit').bind( 'taphold', function( e ) {
            var data = $("#sticky-input").val();
            alert('Notes Saved!');
            localStorage.setItem("sticky", data);
            $(".sticky-text").text(localStorage.getItem("sticky")).show();
      } );  

    } );

    $(".sticky-text").text(localStorage.getItem("sticky")).show();
#stickies li {
    position: relative;
    width: 200px;
    min-height: 100px;
    margin: 25px auto;
    padding: 15px;
    background: #f1f3a2;
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(247,247,210,1)), to(rgba(240,242,155,1)));
    background: -moz-linear-gradient(top, rgba(247,247,210,1), rgba(240,242,155,1));
    -webkit-box-shadow: 0 2px 12px rgba(0,0,0,.5);
    -moz-box-shadow: 0 2px 12px (rgba(0,0,0.5));
    box-shadow: 0 1px 2px #000;
    -webkit-transform: rotate(-.5deg); 
    -moz-transform: rotate(-.5deg); 
    -o-transform: rotate(-.5deg);   
    text-align: center;
    color: #000;
    text-shadow: white 1px 1px 0px;
    list-style: none;
}

#stickies li:nth-child(even) {
    -webkit-transform: rotate(.5deg); 
    -moz-transform: rotate(.5deg); 
    -o-transform: rotate(.5deg);     
}

#stickies li::before {
    content: ' ';
    display: block;
    position: absolute; 
    left: 65px;
    top: -15px;
    width: 75px;
    height: 25px;
    z-index: 2;
    background-color: rgba(243,245,228,0.5);
    border: 2px solid rgba(255,255,255,0.5);
    -webkit-box-shadow: 0 0 5px #888;
    -moz-box-shadow: 0 0 5px #888;
    box-shadow: 2px 2px 2px #000;
    -webkit-transform: rotate(-3deg); 
    -moz-transform: rotate(-3deg); 
    -o-transform: rotate(-3deg); 
}

#stickies li:nth-child(even)::before {
    -webkit-transform: rotate(3deg); 
    -moz-transform: rotate(3deg); 
    -o-transform: rotate(3deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="stickies">
    <li>
        <p class="sticky-text">Hello</p>
        <a id="sticky-edit">Edit</a>
        <a id="sticky-submit">Submit</a>
    </li>
</ul>

现在我需要做的就是弄清楚如何允许用户创建尽可能多的便签,每个便签都有自己的本地存储区域。使用 jquery 可以实现这一点吗?或者使用 php 来实现这一点会更容易吗?

I am creating a stickies reminder application for an iphone website. The goal is to have the user to create as many "stickies" as he wants - all the data would be saved with localstorage.

I have a working prototype of the stickies here:

    $( function() {
        $('#sticky-edit').bind( 'taphold', function( e ) {
            alert( 'You tapped and held!' );
            var thetext = localStorage.getItem("sticky");
            $(".sticky-text").html('<input id="sticky-input" type="text" value="'+thetext+'" />');
      } ); 
      
        $('#sticky-submit').bind( 'taphold', function( e ) {
            var data = $("#sticky-input").val();
            alert('Notes Saved!');
            localStorage.setItem("sticky", data);
            $(".sticky-text").text(localStorage.getItem("sticky")).show();
      } );  

    } );

    $(".sticky-text").text(localStorage.getItem("sticky")).show();
#stickies li {
    position: relative;
    width: 200px;
    min-height: 100px;
    margin: 25px auto;
    padding: 15px;
    background: #f1f3a2;
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(247,247,210,1)), to(rgba(240,242,155,1)));
    background: -moz-linear-gradient(top, rgba(247,247,210,1), rgba(240,242,155,1));
    -webkit-box-shadow: 0 2px 12px rgba(0,0,0,.5);
    -moz-box-shadow: 0 2px 12px (rgba(0,0,0.5));
    box-shadow: 0 1px 2px #000;
    -webkit-transform: rotate(-.5deg); 
    -moz-transform: rotate(-.5deg); 
    -o-transform: rotate(-.5deg);   
    text-align: center;
    color: #000;
    text-shadow: white 1px 1px 0px;
    list-style: none;
}

#stickies li:nth-child(even) {
    -webkit-transform: rotate(.5deg); 
    -moz-transform: rotate(.5deg); 
    -o-transform: rotate(.5deg);     
}

#stickies li::before {
    content: ' ';
    display: block;
    position: absolute; 
    left: 65px;
    top: -15px;
    width: 75px;
    height: 25px;
    z-index: 2;
    background-color: rgba(243,245,228,0.5);
    border: 2px solid rgba(255,255,255,0.5);
    -webkit-box-shadow: 0 0 5px #888;
    -moz-box-shadow: 0 0 5px #888;
    box-shadow: 2px 2px 2px #000;
    -webkit-transform: rotate(-3deg); 
    -moz-transform: rotate(-3deg); 
    -o-transform: rotate(-3deg); 
}

#stickies li:nth-child(even)::before {
    -webkit-transform: rotate(3deg); 
    -moz-transform: rotate(3deg); 
    -o-transform: rotate(3deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="stickies">
    <li>
        <p class="sticky-text">Hello</p>
        <a id="sticky-edit">Edit</a>
        <a id="sticky-submit">Submit</a>
    </li>
</ul>

Now all I need to do is figure out how to allow the user to create as many stickies as they want each with its own local storage area. Is this possible with jquery or would it be easier to use php to accomplish this?

我在 Flash 中做过一次。本地存储区是什么意思?您可以让用户像这样创建任意数量的: http://jsfiddle.net/NegYd/14/ 使用 javascript/jquery。关键是:

function appendSticky(){
     var e= document.getElementById("submittext").value;
     $("#stickies").append("<li>"+e+"</li>");
     $.post("store.php", { text: e} );//you'll have to submit user information
}

和 html:

<input id="submittext" type='text'/>
<input type='submit' value='add note' onClick="javascript:appendSticky();"/>

然后在您的 store.php 中将便签存储到 MySQL 数据库中。 $sql="INSERT.."

我建议使用 float:left; 使用随机 margin-left 值而不是列表来组织便签带来终极的便利贴感觉。或者更好的是,让便利贴可拖放。

I did this in Flash once. What do you mean by local storage area? You can let the user make as many as he wants like this: http://jsfiddle.net/NegYd/14/ using javascript/ jquery. Key being:

function appendSticky(){
     var e= document.getElementById("submittext").value;
     $("#stickies").append("<li>"+e+"</li>");
     $.post("store.php", { text: e} );//you'll have to submit user information
}

and the html:

<input id="submittext" type='text'/>
<input type='submit' value='add note' onClick="javascript:appendSticky();"/>

Inside your store.php you then store the stickies into a MySQL Database. $sql="INSERT.."

I suggest organizing the stickies with float:left; with a random margin-leftvalue rather than a list for the ultimate post-it feel. Or even better, make the post-its drag-and-dropable.
