JavaScript基于ajax编辑信息用法实例
本文实例讲述了JavaScript基于ajax编辑信息的方法。分享给大家供大家参考。具体如下：
//Requiresprototype.js
functionedit(action,obj){
Element.hide(obj);
vartextarea='<divid="'+obj.id+'_editor"><inputtype="text"id="'+obj.id+'_edit"name="'+obj.id+'"value="'+obj.innerHTML+'"size="40">';
varbutton='<inputid="'+obj.id+'_save"type="button"value="SAVE"/><inputid="'+obj.id+'_cancel"type="button"value="CANCEL"/></div>';
newInsertion.After(obj,textarea+button);
Event.observe(obj.id+'_save','click',function(){saveChanges(action,obj)},false);
Event.observe(obj.id+'_cancel','click',function(){cleanUp(obj)},false);
$(obj.id+"_edit").focus();
$(obj.id+"_edit").select();
}
functioncleanUp(obj,keepEditable){
Element.remove(obj.id+'_editor');
Element.show(obj);
if(!keepEditable)showAsEditable(obj,true);
}
functionsaveChanges(action,obj){
varnew_content=escape($F(obj.id+'_edit'));
obj.innerHTML="Saving...";
cleanUp(obj,true);
varsuccess=function(t){editComplete(t,obj);}
varfailure=function(t){editFailed(t,obj);}
varurl='poll-ajax.php?a='+action;
varpars='id='+obj.id+'&content='+new_content;
varmyAjax=newAjax.Request(url,{method:'post',postBody:pars,onSuccess:success,onFailure:failure});
}
functioneditComplete(t,obj){
obj.innerHTML=t.responseText;
showAsEditable(obj,true);
}
functioneditFailed(t,obj){
obj.innerHTML='Sorry,theupdatefailed.';
cleanUp(obj);
}
希望本文所述对大家的javascript程序设计有所帮助。
