在我的项目中,我正在使用select2组件。对于我选择的元素,我添加了图标和说明。代码是这样的:
function format(profile_opt) {
return profile_opt.text + "<br><span class=\"description_select2\"><i>" + $(profile_opt.element).attr('title') + "</i></span><br>" +
($(profile_opt.element).attr('start').length==0?'':('from: <b>' + $(profile_opt.element).attr('start') + '</b>')) + ($(profile_opt.element).attr('end').length==0?'':(' to: <b>' + $(profile_opt.element).attr('end') + '</b>')) +
" <a href=\"#\" onclick=javascript:showUrlInDialogWithOptionId(\"<%=request.getContextPath()%>/assignments_date_set.jsp\",\"" + profile_opt.id + "\",\"" + $(profile_opt.element).attr('start') + "\",\"" + $(profile_opt.element).attr('end') + "\")>" +
"<img src=\"images/icons/small/grey/clock.png\" title=\"Set start and end assignment dates\" alt=\"Set start and end assignment dates\" class=\"clock\" id=\"clock\" width=\"20px\" height=\"20px\"></a>";
}
function format2(profile_opt){
return profile_opt.text +"<br><span class=\"description_select2\"><i>" + $(profile_opt.element).attr('title') + "</i></span>";
}
$('#selected_profiles').select2({ allowSelectAllNone: true, closeOnSelect:false, width: '600px', placeholder: 'Click to select',
formatResult: format2,
formatSelection: format,
escapeMarkup: function(m) { return m; }
});
我的问题是:如何将工具提示设置为格式选项元素的子字符串。我的意思是我只需要开始提供工具提示而不是整个语法与html里面。提前感谢您的帮助。
答案 0 :(得分:1)
在select2
构造函数中添加以下两个参数:
formatResult: format,
formatSelection: format
然后在select2构造函数之外定义format
函数,如下所示:
function format(item) {
var originalText = item.text;
return "<div title ='" + originalText + "'>" + originalText + "</div>";
}
