从JavaScript中的每个数组删除第一个元素

Question

I have a multi dimensional array like this.

 var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']]

I want to remove all the first element to get a result like this.

var myArray = [['1','2.33','44'],['1','2.33','44'],['1','2.33','44']]

Please Help me. Thanks

Answer 1

Use .forEach to loop over the nested arrays and then .splice them. Splice will remove the first item in the nested array and effect the current array.

 var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']]; myArray.forEach(array => array.splice(0,1)); console.log(myArray); 

Base on the comment you can also use .shift() function to remove the first item.

 var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']]; myArray.forEach(array => array.shift()); console.log(myArray); 

Answer 2

You can try this

 var myArray = [['aaa','1','2.33','44'],['bbb','1','2.33','44'],['ccc','1','2.33','44']]; var done = function(){ console.log(myArray); }; myArray.forEach(function(array){ array.splice(0,1); done(); }); 

Output

[['1','2.33','44'],['1','2.33','44'],['1','2.33','44']];
