如何通過名字

Question

我試圖通過名字來從數組中刪除多個元素從數組中刪除多個元素

這是我的代碼

var mularr = ["jQuery","JavaScript","HTML","Ajax","Css"]; 
var itemstoRemove = ["jQuery","HTML"]; 
for(var i=0;i<itemstoRemove.length;i++) 
{ 
    mularr.splice($.inArray(itemstoRemove, mularr),1); 
} 
alert(mularr); 

有誰請讓我知道如何刪除多個按名稱排列數組中的元素？

Answer 1

你只需要遍歷itemsToRemove -

var mularr = ["jQuery","JavaScript","HTML","Ajax","Css"]; 
 
var itemstoRemove = ["jQuery","HTML"]; 
 
for(var i=0;i<itemstoRemove.length;i++) 
 
{ 
 
    mularr.splice($.inArray(itemstoRemove[i], mularr),1); // note the [i] 
 
} 
 
console.log(mularr);

var main = [1,2,3,4,5,1,2,3,9]; // main array                
var removedItemsIndex = [0,2,4]; // array of index to delete of main array 
var result=[]; 
for(var i=0;i<main.length;i++){ 
    if(removedItemsIndex.indexOf(i)==-1) 
    result.push(main[i]) 
} 
console.log(result)
