<img src="http://ww... is there a simple way just to get image url? Maybe something with .match?

Answer 1

这是我做的方式..

var findImg = entry.content;
var img = $(findImg).find('img').eq(0).attr('src'); //i use jquery to find 1st img src

function imgFeed(){
    var defaultImg= "images/default.jpg"; 
    if(img==null){
        return defaultImg;  // if cant find any, show default image src
    }else{
        return img;
    }
}
yourElement.append('<img width="194" height="91" src="'+imgFeed()+'" alt="#" />');
