Novice Seeking Advice

I am a beginner of the Web front-end novice one. Now I'm having a problem.

<p><a href= "#" class= "Head_news_1" onclick= "return false" > big title 1</a></p><p><a href= " # "class=" Head_news_1 "onclick=" return false "> big title 2</a></p><p><a href=" # "class=" Head_news_1 "Onclick=" return false "> big title 3</a></p><p><a href=" # "class=" Head_news_1 "onclick=" return False "> big title 4</a></p>

I got four URL values from the XML document, ready to be assigned to the four links above. Use $ (". Head_news_1")

Get the Object

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/6B/E8/wKioL1U6BRiyAqqiAADo_IccKRM310.jpg "title=" QQ picture 20150424165232.png "alt=" Wkiol1u6briyaqqiaado_icckrm310.jpg "/>

But ready

$ (". Head_news_1") [0].attr ("href", "Http://XXXXX")

Time to find that the $ (". Head_news_1") [0] value obtained is not an object obtained directly through $ (". Class"), which is a string. The attr operation cannot be implemented. I don't know how to solve this problem. Because there are a lot of links, a configuration class is not appropriate, please also advise how can you convert this string into an object that can be manipulated using attr?
