javascript 数据存储的常用函数总结

数据存储的常用函数

存入数组不重复值

function pushtoArray(myarr,mydata){ if(myarr.length==0){ myarr.push(mydata); }else{ var oktopush=true; for(var ele in myarr){ if(myarr[ele]==mydata){ oktopush=false; } } if(oktopush){ myarr.push(mydata); } } return myarr; }

删除数组中的元素

Array.prototype.remove = function(val) { var index = this.indexOf(val); if (index > -1) { this.splice(index, 1); } };

存入对象到localStorage

function setObjectStorage(itemname,myobj){ localStorage.setItem(itemname, JSON.stringify(myobj)); } function getObjectStorage(itemname){ return JSON.parse(localStorage.getItem(itemname)); }
