【问题描述】:
所以我有一个代码可以在 phonegap 中正常运行 css 和 html,但是 javascript 项目不起作用。例如,我正在制作一个待办事项应用程序,但该按钮不会保存我的新项目,或者单击删除。
css代码
body
{
font-family: Verdana, Arial;
font-size: 18px;
background-color:#D4D0B4;
}
h1
{
background-color:#626b5e;
font-size:1em;
color:#F5F6F5;
line-height:2em;
text-align:center;
}
#newTaskInput, #addNewTask
{
display:block;
width:98%;
margin-top:5px;
margin-left:auto;
margin-right:auto;
background-color:#757769;
border:0;
height;2em;
font-size:1em;
color:#F5F6F5;
}
#taskList
{
margin-top:10px;
}
#taskList > li
{
background: -webkit-linear-gradient(#FFF, #F6F6F7);
background: -o-linear-gradient(#FFF, #F6F6F7);

border:1px solid #BBB6AF
line-height:2em;

margin-top:2px;
}
#taskList span
{
margin-left:5px;
}
.done
{
text-decoration:line-through;
opacity:0.5;
}

if(taskTouchStart == taskTouchEnd)
{
if(taskTouchStartX < taskTouchEndX)
{
if($this.hasClass('done'))
{
$this.removeClass('done');
}
else
{
$this.addClass('done');
}
}
else
{
taskList = $.grep(taskList, function(e){ return e.key != taskTouchEnd;});
if(window.localStorage)
{
window.localStorage.setItem('taskList', JSON.stringify(taskList));
}
$end.remove();
}
}
});
});
【问题讨论】:
-
标题中的真正意思是 Java 吧?
-
我现在没有发现错误,但 $( document ).ready(function(){ 触发了吗?我通常在行之间写下警报,以便知道它在哪里停止工作跨度>
