将html代码传递给php时出现的对象HTMLDivElement-Angular

我们在变量中有html代码。我们想用 php 并保存在mysql中。

home.ts 侧码:

this.divCodesub = document.getElementById(this.selectedDivCodesub);
console.log (this.divCodesub);

数据输入控制台.log是:

<div id="0"><div id="change_color" class="heading-back context_menu"><div class="row"><div contenteditable="true" class="col-md-12 heading-sec context_menu">Hi there, Im <span contenteditable="true" class="head-clr">STACK</span></div><div contenteditable="true" class="col-md-12 heading-sec context_menu">Smart, simple and responsive.</div></div></div></div>

divCode:[对象HTMLDivElement] ,此消息出现在网络中。

我们怎么才能通过呢?

编辑:1 如何将变量发送到php,请参见下面的代码-

代码:

    'divI='+this.list[this.selectedDivCodesub].div_id+'&divCode='+this.divCodesub;
            this._updateSection.callService(api,params).subscribe(data=>{
 ...
});

service.ts 代码:

 callService(api,params){
        var headers = new Headers();
        headers.append('Content-Type', 'application/x-www-form-urlencoded');
        return this._http.post(this._url+api,params+"&"+this.randomno,{headers:headers})
               .map((response:Response) => response.json());
    }
