html傳值方法

傳值的方法如下：

方法一：URL傳參（？後面的參數）（）

window.location.href = "https://www.google.com/search?q=hello&oq=hello"

 

function parseURL(url){

    var url = url.split("?")[1];

    var para = url.split("&");

    var len = para.length;

    var res = {};

    var arr = [];

    for(var i=0;i<len;i++){

        arr = para.split("=");

        res[arr[0]] = arr[1];

    }

    return res;

}

方法二：cookie傳參

function setCookie(cname,cvalue,exdays){

    var d = new Date();

    d.setTime(d.getTime() + (exdays*24*60*60*1000));

    var expires = "expires=" + d.toUTCString();

    document.cookie = cname + "=" + cvalue + "; " + expires;

}

 

function getCookie(cname){

    var name = cname + "=";

    var ca = document.cookie.split(";");

    for(var i=0;i<ca.length;i++){

        var c = ca[i];

        while(c.charAt(0)==' '){

            c = c.substring(1); 

        }

        if(c.indexof(cname) == 0){

            return c.substring(name.length,c.length);

        }

    }

    return "";

}

方法三：H5中Web Storage中的localStorage對象

 

localStorage.setItem("lastname","lu");

或者

localStorage.lastname = "lu";

 

localStorage.getItem("lastname");
