javascript - 从二维 Javascript 数组中删除一个项目

Question

我有一个像这样的简单数组:

  var CutRoadArray = [
            ['Location', '_Location'],
            ['Applicant Info', '_ApplicantInfo'],
            ['Details', '_ApplicationDetails'],
            ['Bond Info', '_BondInfo'],
            ['Attachments', '_Attachments'],
            ['Review', '_ReviewA']
        ];

我想检查该数组是否包含该条目

['Bond Info', '_BondInfo'],

如果有，请将其删除。在一个单独的场景中，我想搜索相同的内容，如果不存在，则将其添加到某个索引处。

尝试了各种方法，都没有成功。任何帮助将不胜感激。

我尝试实现这一目标的方法之一是:

Array.prototype.remove = function () {
            var what, a = arguments, L = a.length, ax;
            while (L && this.length) {
                what = a[--L];
                while ((ax = this.indexOf(what)) !== -1) {
                    this.splice(ax, 1);
                }
            }
            return this;
        };


function indexOfRowContainingId(id, matrix) {
        var arr = matrix.filter(function (el) {
            return !!~el.indexOf(id);
        });
        return arr;
    }

然后调用类似的内容:

 var bond = indexOfRowContainingId('_BondInfo', CutRoadArray);
   if (bond.length > 0) {
                    var ar = CutRoadArray.remove("['Bond Info', '_BondInfo']");
               console.log(ar);
    }

Answer 1

试试这个:

var CutRoadArray = [
        ['Location', '_Location'],
        ['Applicant Info', '_ApplicantInfo'],
        ['Details', '_ApplicationDetails'],
        ['Bond Info', '_BondInfo'],
        ['Attachments', '_Attachments'],
        ['Review', '_ReviewA']
    ];
var testElem = ['Bond Info', '_BondInfo'];

for(var i=0; i<CutRoadArray.length; i++){
  var temp = CutRoadArray[i].toString();
  if(temp === testElem.toString()){ 
     //remove element from array
     CutRoadArray.splice(i, 1);
     break;

  }

}

console.log(CutRoadArray);
