将后台JSON数据填充Form表单

$.fn.populateForm = function(data){ return this.each(function(){ var formElem, name; if(data == null){this.reset(); return; } for(var i = 0; i < this.length; i++){ formElem = this.elements[i]; //checkbox的name可能是name[]数组形式 name = (formElem.type == "checkbox")? formElem.name.replace(/(.+)\[\]$/, "$1") : formElem.name; if(data[name] == undefined) continue; switch(formElem.type){ case "checkbox": if(data[name] == ""){ formElem.checked = false; }else{ //数组查找元素 if(data[name].indexOf(formElem.value) > -1){ formElem.checked = true; }else{ formElem.checked = false; } } break; case "radio": if(data[name] == ""){ formElem.checked = false; }else if(formElem.value == data[name]){ formElem.checked = true; } break; case "button": break; default: formElem.value = data[name]; } } }); };

调用方式：$(“#formId”).populateForm(data);
