javascript - 使用javascript在括号内添加字符串

Question

“AddMoreRowsWithNo('SnapIII_btnEquipmentAddMore', 'SnapIII_TBLAditionalEquipment', 'SnapIII_trAdditionalEquipment', 'SnapIII_tdEquipmentNo')”

我需要在字符串内的右括号之前添加值。例如，

AddMoreRowsWithNo('SnapIII_btnEquipmentAddMore', 'SnapIII_TBLAditionalEquipment', 'SnapIII_trAdditionalEquipment', 'SnapIII_tdEquipmentNo', valCount);

Answer 1

这是带有正则表达式和替换函数的函数，第一次将传递 func 的名称作为变量，第二次 - 你的 func 参数

 function addParams(funcStr, paramsArrayToAdd){
   var isFirstCall = false;
   return funcStr.replace(/[^\)\(]+/g,function(str){
      if(!isFirstCall){
        isFirstCall = true;
        return str;
      }else{
        return str.length > 0 ? str + "," + paramsArrayToAdd.join(",") : paramsArrayToAdd.join(",");
      }
   });
}

使用示例

    var str = addParams("AddMoreRowsWithNo('SnapIII_btnEquipmentAddMore', 'SnapIII_TBLAdditionalEquipment', 'SnapIII_trAdditionalEquipment', 'SnapIII_tdEquipmentNo')",["'param1'","'param2'"])
    console.log(str);//AddMoreRowsWithNo('SnapIII_btnEquipmentAddMore', 'SnapIII_TBLAdditionalEquipment', 'SnapIII_trAdditionalEquipment', 'SnapIII_tdEquipmentNo','param1','param2')
