jquery change div text
提问by gubby
'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
<div class="widget-head ui-widget-header" style="cursor:move;height:20px;width:130px">'+
'<span id="'+span_id+'" style="float:right; cursor:pointer" class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
dialog_title+'</div></div>
I have a div constructed using the above string. After some processing..I have to change the dialog_title in the above div. I am trying to do it with the following code
我有一个使用上述字符串构造的 div。经过一些处理..我必须更改上面div中的dialog_title。我正在尝试使用以下代码
$('#'+div_id+' .widget-head').text("new dialog title");
While this changes the dialog title..it removes the span element which is used to open a dialog box.
虽然这会更改对话框标题..它删除了用于打开对话框的 span 元素。
I tried to the replaceWith method with a string with new dialog title..but that shows NaN for title and the span though visible cant be clicked(are events disabled?)
我尝试使用带有新对话框标题的字符串的 replaceWith 方法..但是显示标题为 NaN 和跨度虽然无法单击可见（是否禁用了事件？）
How do I change the text without losing the span and ability to click it.
如何在不丢失跨度和单击它的能力的情况下更改文本。
Thanks in advance.
提前致谢。

Put the title in its own span.
将标题放在自己的范围内。
<span id="dialog_title_span">'+dialog_title+'</span>
$('#dialog_title_span').text("new dialog title");

I think this will do:
我认为这会做：
$('#'+div_id+' .widget-head > span').text("new dialog title");

best and simple way is to put title inside a span and replace then.
最好和最简单的方法是将标题放在一个跨度内然后替换。
'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
<div class="widget-head ui-widget-header"
style="cursor:move;height:20px;width:130px">'+
'<span id="'+span_id+'" style="float:right; cursor:pointer"
class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
'<span id="spTitle">'+
dialog_title+ '</span>'
'</div></div>
now you can simply use this:
现在你可以简单地使用这个：
$('#'+div_id+' .widget-head sp#spTitle').text("new dialog title");
