方法一:加timeout定时器的get或getJSON函数。
方法二:利用adjax函数处理。
function get_device_list(){
{% autoescape off %}
svcs ={{servers}};
{% endautoescape %}
for (var i=0; i< svcs.length; i++)
{
var svc = svcs[i];
var loadid = ‘#tryloading’ + i.toString();
var url = ‘http://’ + svc + ‘/listalldevices.json’;
if(0){
$.get(url, {}, handle_device_list(svc, loadid));
setTimeout(handle_device_list_error(svc, loadid), 10000);
}else{
var req = {‘url’:url,
‘data’:{},
‘type’:’GET’,
‘datatype’:’json’,
‘success’:handle_device_list(svc, loadid),
‘error’:handle_device_list_error(svc, loadid)};
$.ajax(req);
}
}
}
在bootstrap中,常使用这样的方式来表示hover和normal的状态。但这样可能会导致页面存在页面跳转的刷新效果,这种效果不一定是符合我们预期,所以有时需要屏蔽这种效果,因此推荐如下两种使用方法。
第一种:<a href=”javascript:void(0);” onclick=”function()”></a>
第二种:
<a href=”javascript:;” onclick=”function()”></a>
第一种void(0)值是计算一个空值,第二种是执行一个空js串(注意双引号内的冒号和逗号),在W3C中不推荐在href语句中执行JS脚本,因此使用onclick的方式响应本地脚本,才是符合W3C的推荐。
第一种:针对类属性,进行遍历所有项,并为其添上click属性。
$(“.stopall”).each(function(index){
$(this).click(function(e) {
$(‘#msgtxt-dialog’).modal()
stop_all_spider($(e.currentTarget))
});
})
$(“.startnew”).each(function(index){
$(this).click(function(e) {
var target = $(e.currentTarget)
var host = target.parent().parent().children(“td:nth-child(1)”).html();
var prj = target.parent().parent().children(“td:nth-child(2)”).html();
var spider = target.parent().parent().children(“td:nth-child(3)”).html();
var nodeParent = $(“#startnew-dialog”);
var label1 = nodeParent.find(“#host”);
var label2 = nodeParent.find(“#project”);
label1.html(host);
label2.html(prj);
$(‘#startnew-dialog’).modal()
});
})
第二种:
<!– 按钮触发模态框 –>
<button class=”btn btn-primary btn-lg” data-toggle=”modal”
data-target=”#myModal”>
开始演示模态框
</button>
<!– 模态框(Modal) –>

<div class=”modal-content”>
<div class=”modal-header”>
<button type=”button” class=”close”

×
</button>
<h4 class=”modal-title” id=”myModalLabel”>
模态框(Modal)标题

</div>
<div class=”modal-body”>
在这里添加一些文本
</div>
<div class=”modal-footer”>
<button type=”button” class=”btn btn-default”
data-dismiss=”modal”>关闭
</button>
<button type=”button” class=”btn btn-primary”>
提交更改
</button>
</div>

如何遍历jsonc对象?其实方法很简单。
比如有如下json对象:
var obj ={“name”:”冯娟“,”password”:”123456″,”department”:”技术部“,”sex”:”女“,”old”:30};
遍历方法:
for(var p in obj)
{
str = str+obj[p]+’,’;
return str;
}
在django的模板中,如果你输出一些特殊字符如”<> “‘”即HTML中会出现的特殊标签及冒号引号等,则它会自动把相关符号进行转义,导致与你所需不致,故在必要的时候需要关闭它。
svcs2是我们需要通过模板输出svcs的效果,由于autoescape的作用影响,会输出如下
需要对autoescape的功能进行关闭,如下图。
终于符合预期输出了。
{% autoescape off %}
svcs2 = {{ servers }};
{% endautoescape %}
sudo yum remove ibus --会将所有的输入法删除
安装ibus,ibus-table
sudo yum install ibus ibus-table --这样只会安装ibus的输入框架
sudo yum install ibus-table-wubi
yum install “@Chinese Support”
安装中文语言支持包
yum -y groupinstall chinese-support解决中文显示问题
yum -y install Deployment_Guide-zh-* lv-* stardict*
yum -y install scim*安装中文输入法
yum install scim
yum install scim-pinyin
yum install “@Chinese Support” centos6.6
重启,然后在编辑窗口按ctrl+space键即可呼出输入法。
