如何在字符串數組中使用正則表達式匹配？

Question

我想這樣：當輸入的值匹配我的數組的值時，寫入匹配值。

所以這是我的代碼：

//我的陣列，如下所示：

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

我的另一個陣列：myarray= ["RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"]

例如;當寫RAB *到textare，我應該看到，隨着「RAB」

我猜，我開始代碼應該如下：

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 %" 
     } 
    } 

我該怎麼辦？ 請。

Answer 1

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>

Answer 2

@鷹，我相信這是輸入到checkNames。如果是這樣，這裏是我的解決方案 -

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)); 
    } 
} 

接受此答案，如果它解決您的要求。
