我实现了一个淘汰赛的foreach结合,在同一个页面多个模板,范例之一,这里给出的,我感兴趣是找出当块呈现完毕后,我曾尝试afterRender和afterAdd,但我想它运行的每个元素,而不是整个循环结束后.

<ul data-bind="foreach: {data: Contacts, afterAdd: myPostProcessingLogic}">
  <li>
    <div class="list_container gray_bg mrgT3px">
      <div class="list_contact_icon"></div>
      <div class="contact_name"><span data-bind="text: first_name"></span> <span data-bind="text: last_name"></span></div>
      <div class="contact_number"><span data-bind="text: value"></span></div>
      <div class="callsms_container">
        <a href="#notification-box" class="notifcation-window">
          <div class="hover_btn tooltip_call">
            <div class="hover_call_icon"></div>
            <span>Call</span></div>
        </a>
        <a class="sendsms" href="#sendsms" rel="#sendsms">
          <div class="hover_btn tooltip_sms">
            <div class="hover_sms_icon"></div>
            <span>SMS</span></div>
        </a>
        <a href="#">
          <div class="hover_more_btn"></div>
        </a>
      </div>
      <!-- close callsms container -->
      <div id="notification-box" class="notification-popup">
        <a href="#" class="close"><img class="btn_close" src="images/box_cross.png" /></a> <img class="centeralign" src="images/notification_call.png" /> <span>Calling... +44 7401 287366</span> …

我正在尝试删除p带有data-spotid属性的标签

        $dom = new DOMDocument();
        @$dom->loadHTML($description);
        $pTag = $dom->getElementsByTagName('p');

        foreach ($pTag as $value) {
            /** @var DOMElement $value */
            $id = $value->getAttribute('data-spotid');
            if ($id) {
                $value->parentNode->removeChild($value);
            }
        }

但是当我删除孩子时，它正在重新索引 dom。假设我有 8 个项目，我第一次删除它会重新索引它，第二个元素将成为第一个，它不会删除它将转到第二个，现在是第三个元素。

我正在从php转换数组到json json_encode().如果我为一个数组编码它我可以解码它,但是当它是这样的:array('a'=>array(0=>array(),1=>array()))它返回{"a":[[],[]]}

当我解码它时,我得到以下错误

Catchable fatal error: Object of class stdClass could not be converted to string

我不知道如何处理$ .post()上的404错误？

$.post(url, data, function(returnedData) {

它只能处理成功数据,但我也想处理404错误.我知道如何用ajax做但不知道这个功能请帮忙.

    function returnData(url,data,type){
        $.post(url, data, function(returnedData) {
        if(type == "contacts")
        {   
        ko.applyBindings(new ContactsViewModel(returnedData,"#KnockOutContacts",url,data),$("#KnockOutContacts")[0]);   
        ko.applyBindings(new ContactsViewModel(returnedData,"#ContactDetails",url,data),$("#ContactDetails")[0]);   
        }
        else if(type == "logs")
        {
        alert(returnedData);
        alert(1);
        ko.applyBindings(new LogsViewModel(returnedData,url,data),$("#KnockOutLogs")[0]);   
        }
        else if(type == "sms")
        {
            ko.applyBindings(new SmsViewModel(returnedData,"#KnockOutSmsData",url,data),$("#KnockOutSmsData")[0]);  
            ko.applyBindings(new SmsViewModel(returnedData,"#KnockOutSms",url,data),$("#KnockOutSms")[0]);  
        }
        else if(type == "calendar")
        {
        ko.applyBindings(new CalendarViewModel(returnedData,"#KnockOutCalendar",url,data),$("#KnockOutCalendar")[0]);   
        }
        else if(type == "search")
        {
        ko.applyBindings(new SearchViewModel(returnedData,"#searchbox",url,data),$("#searchbox")[0]);   
        }
        else if(type == "location")
        {
        ko.applyBindings(new LocationViewModel(returnedData,"#KnockOutMaps",url,data),$("#KnockOutMaps")[0]);   
        }
        else if(type == "photos")
        {
        ko.applyBindings(new PhotosViewModel(returnedData,"#photogallary",url,data),$("#photogallary")[0]); 
        ko.applyBindings(new PhotosViewModel(returnedData,"#PhotosDown",url,data),$("#PhotosDown")[0]); 
        }
    });
}

我基本上应用绑定当我得到数据,但当我没有得到数据,它不会进入成功函数,这就是打破我的js.
