回答1:

You are doing wrong concatenation, Where you assigning the innerHTML to content. It should be :

document.getElementById("content").innerHTML +="<br>"+ item.title + "<br>" +"<a href='"+item.title+"'>Google</a>";

Your function should be :

function hndlr(response) {
    for (var i = 0; i < response.items.length; i++) {
        var item = response.items[i];
        // in production code, item.htmlTitle should have the HTML entities escaped.
        document.getElementById("content").innerHTML +="<br>"+ item.title + "<br>"   +"<a href='"+item.title+"'>Google</a>" ;

    }
}

Your problem is from this line +"<a href='+item.title'>Google</a>"

since your outter enclosing apostrophe is " then for you to maintain your real values of variable is for your make sure that the variables or executables are not inside that enclosing outer " .

So this should work out for you

document.getElementById("content").innerHTML +="<br>"+ item.title + "<br>"   +"<a href='"+item.title+"'>Google</a>" ;

observe the href='"+ item.title+ "'
