[英]JavaScript single quotes and double quotes in append() - fullcalendar external-events
I am creating a drop-down menu which generates several external-events (depending on your choice) that can be drop on the fullcalendar. 我正在创建一个下拉菜单,该菜单会生成多个外部事件(取决于您的选择),这些事件可以放在完整日历上。 I need to append several event divs to another div in the success part of ajax.
我需要在ajax的成功部分中将几个事件div附加到另一个div。
The problem is that I can't properly write the single and double quotes in the string that must be placed in the append function. 问题是我不能在必须放在append函数中的字符串中正确编写单引号和双引号。
The div should be rendered like this after append: div应该在追加之后呈现为:
<div class='fc-event' data-event='{"id": 1, "title": "This is event 1"}'>My Event 1</div>
Here is the function for listening to changes in drop-down list and generate external-events: 这是侦听下拉列表中的更改并生成外部事件的功能:
$("#category").change(function () {
$('#listAct').html("");
$.ajax({
type: "POST",
url: 'SearchActivities.php',
data: { CategoryName: $("#category").find("option:selected").val() },
success: function (data) {
var result = $.parseJSON(data);
var arraysize = result.length;
var i, ActTitle;
for (i = 0; i < arraysize; i++) {
ActTitle = result[i]['ActTitle'];
var eventdetails = '{"id":1,"title":"This is event 1"}';
$('#listAct').append('<div class="fc-event" data-event=' + eventdetails + '>' + ActTitle + '</div>');
}
/* initialize the external events
-----------------------------------------------------------------*/
$('#listAct').find('.fc-event').each(function () {
// make the event draggable using jQuery UI
$(this).draggable({
zIndex: 999,
revert: true, // will cause the event to go back to its
revertDuration: 0 // original position after the drag
});
});
}
});
});
I try to place all the necessary values in a varialbe (eventdetails) and then use it in the append content but if you want to place the data-event content directly in the append function there is no problem. 我尝试将所有必要的值放在varialbe(事件详细信息)中,然后在附加内容中使用它,但是如果您想将数据事件内容直接放置在附加函数中,就没有问题。
The drop-down list : 下拉列表:
<form>
<label style="color: black" for="category">Select Category</label>
<select id="category" name="category">
<option value=""></option>
<option value="Attractions, Nature Park">Attractions, Nature Park</option>
<option value="Underwater Activities">Underwater Activities</option>
<option value="Museums and Sites">Museums and Sites</option>
</select>
</form>
<div id="listAct">
<div class='fc-event' data-event='{"id": 1, "randomProperty": "foobar", "title": "This is event 1"}'>My Event 1</div>
</div>
Change this line 更改此行
$('#listAct').append('<div class="fc-event" data-event=' + eventdetails + '>' + ActTitle + '</div>');
to 至
$('#listAct').append('<div class="fc-event" data-event=\'' + eventdetails + '\'>' + ActTitle + '</div>');
Using \\'
will cause the single quotes to be appended to the string and you'll end up with what you want: 使用
\\'
将导致单引号被附加到字符串,您将得到所需的结果:
<div class='fc-event' data-event='{"id": 1, "title": "This is event 1"}'>My Event 1</div>
instead of 代替
<div class='fc-event' data-event={"id": 1, "title": "This is event 1"}>My Event 1</div>
Edit: To use a variable called title
in the eventdetails
variable, use 编辑:要在
eventdetails
变量中使用名为title
的变量,请使用
var eventdetails = '{"id":1,"' + title + '":"This is event 1"}';
