如何在锚标记中使用onclcik和href并仅使onclick有效。href仅适用于Google抓取

Question

In my website when i click on images it opens new page using onclcik openpopup(user defined function)

my problem is google will not index onclcik urls,it only index href urls.

So i want to use use onclcik and href in anchor tag and make only onclick work.href is only for Google crawling purpose only my code is as below

var imgurl = "http:"+lcurl+touch_id+".jpg";
                 var data = "<div id=charm_"+touch_id+" data-charmid="+touch_id+" data-vis="+bgid+" data-vid="+seid+" data-vtitle="+vtitle_url+" data-title="+title_url+" style='float:left;' class='mdl-cell mdl-cell--4-col charm-wrapper'>\n\
                <div class='mdl-card-wrapper charm-inner'>\n\
                  <div class='demo-card-wide mdl-card mdl-shadow--8dp'>\n\
                        <div class='mdl-card__media'>\n\
                        "+locicon+" \n\
                      <a href="popupurl" id='myAnchor' > \n\
                      <div style='position:relative;'>\n\
                      <div style='position:absolute;z-index:9;right:0px;bottom:0px;'><img width=32px src="+cf_assets+"img/hanger.png></div>\n\
                       <div id=imagearea_"+touch_id+" title='"+title+"' class='imagearea loading'>\n\

Fix your code. Place the elements in quotes. Work correctly with quotes.

    var imgurl = "http:"+lcurl+touch_id+".jpg";
    var data = "<div id='charm_"+touch_id+"' data-charmid='"+touch_id+"' data-vis='"+bgid+"' data-vid='"+seid+"' data-vtitle='"+vtitle_url+"' data-title='"+title_url+"' style='float:left;' class='mdl-cell mdl-cell--4-col charm-wrapper'><div class='mdl-card-wrapper charm-inner'><div class='demo-card-wide mdl-card mdl-shadow--8dp'><div class='mdl-card__media'>"+locicon+"<a href='"+popupurl+"' id='myAnchor' ><div style='position:relative;'><div style='position:absolute;z-index:9;right:0px;bottom:0px;'><img width='32px' src='"+cf_assets+"img/hanger.png'></div><div id='imagearea_"+touch_id+"' title='"+title+"' class='imagearea loading'></div></div></a></div><div class='mdl-card__title'><div class='right-charm'><div class='social-share'>"+copycontent+""+watsapp+"<a onclick='sharetofb(\'"+ct_domain+socialshare_url+"\');' title='Facebook' id='fb"+touch_id+"' class='fb_share'></a><a onclick='sharetotwitter(\'"+ct_domain+socialshare_url+"\');' title='Twitter' id='tw"+touch_id+"' class='tw_share'></a></div></div><div class='icharm'><h2 class='mdl-card__title-text'>"+subtitle+"</h2><div class='mdl-card__subtitle-text'>"+title+"</div><div id='vid_"+touch_id+"' class='mdl-card__subtitle-videoname'>"+videoname+"</div></div></div></div></div></div>";

    $('#main-home-page-inner').add(HTML(data));
    callcloudinary(imgurl,title,touch_id);
    callmasonry();

    if(i == setarr.length-1)
    {
        localStorage.touchids=touchid_arr.join(",");
        localStorage.searchresults=gcharmarr.join(",");
    }
    }
} // WHY????

$('myAnchor').on('click',function(ev){ 
ev.preventDefault();
openpopup(ev.target.getAttribute("popupurl"));
sendpym(ev.target.getAttribute("data-charmid"));

You can easily do this by returning false from the handler function at the end.

Refer to this post for more details

Also, you can use something like this if you are using JQuery:

$('a').on('click',function(e){ 
     e.preventDefault();
     // Do your other stuff.
});

In this example I am targeting your anchor tag by tagname. Add a class or ID instead.
