如何在字符串数组中使用正则表达式匹配？

Question

我想这样：当输入的值与我的数组的值匹配时，写入匹配值。

所以这是我的代码：

//我的数组如下：

var checkNames = (document.getElementById("KPIorCounterList").value.split("\n").map(element => element.trim())).filter(v=>v != "");

我的另一个数组：myarray= ["RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"]

例如；将 RAB* 写入 textare 时，我应该看到，从 "RAB"

开始

我猜，我的代码应该是这样的：

  for (var i = 0; i < checkNames.length; i++) {
                    for (var j = 0; j < myarray.length; j++) {
           // var str = myarray[j].split(" "); // I am not sure for his.

            I want to this for here : (pseudo code)
            for example checkName[i] == RAB*
            if (checkName[i].match("match condition") == myarray[j])
            alert(myarray[j]);
            //I should show output myarray[j] == RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"
       }
    }

我该怎么办？请..

Answer 1

@eagle，我相信这是 checkNames 的输入。如果是这样，这是我的解决方案 -

var checkNames = ['RAB*'];
var myarray = ["RAB Video call drop %","RAB PS R99 drop % ","RAB PS HSDPA drop %"];

for (var i = 0; i < checkNames.length; i++) {
    for (var j = 0; j < myarray.length; j++) {
        var formatRegExpr = checkNames[i].replace('*','.*');
        var re = new RegExp(formatRegExpr, 'g');
        alert(myarray[j].match(re));
    }
}

如果能解决您的需求，请采纳此答案。

Answer 2

function check(){
var checkNames = (document.getElementById("KPIorCounterList").value.split("\n").map(element => element.trim())).filter(v=>v != "");
var myarray = ["RAB Video call drop %", "RAB PS R99 drop % ", "RAB PS HSDPA drop %"]
for (var i = 0; i < checkNames.length; i++) {
  console.log("results for", checkNames[i])
  for (var j = 0; j < myarray.length; j++) {

      var matchString = myarray[j].match(new RegExp(checkNames[i].replace('*','.*')));
    if (matchString && myarray.indexOf(matchString[0])!==-1) {
      console.log(myarray[j]);
    }
    //I should show output myarray[j] == RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"
  }
}
  }

<textarea id="KPIorCounterList"></textarea>
<button onclick="check()">Check</button>
