每點(diǎn)一次 就添加一次數(shù)據(jù) 反之可以去除

結(jié)算那根據(jù)json的數(shù)據(jù)算出來(lái)就行了

javascript如何實(shí)現(xiàn)淘寶商品列表里面的分類超過(guò)一行后用一行顯示，點(diǎn)擊更多后會(huì)把超出的部分顯示出來(lái)。

javascript調(diào)用商品信息，沒(méi)有反應(yīng)。高手幫看下。那里出了問(wèn)題。10個(gè)商品中就有3個(gè)沒(méi)有反應(yīng)的。感動(dòng)中

這些類似很亂的標(biāo)簽和提示應(yīng)該是用后臺(tái)程序顯示的，可以看到里面有明顯的出錯(cuò)信息，建議查看后臺(tái)程序接口是否有錯(cuò)誤。

用javascript怎么一次計(jì)算多個(gè)商品總價(jià)

是要多個(gè)值相加求和么？ 舉個(gè)例子：兩個(gè)值相加，第一個(gè)值的id定為fId、第二個(gè)值的id定為sId。JavaScript中寫個(gè)方法

JavaScript...

function sum(){

var id1=document.getElementById("fId").value;

var id2=document.getElementById("sId").value;

//兩個(gè)值相加即可，注意轉(zhuǎn)換為double型的

}

/JavaScript

然后jsp下面在調(diào)用這個(gè)方法就好了 在哪調(diào)用就是你的事了
