Question

我输入的标签是收音机类型

#! /bin/bash

    entra_in_dir(){
        cd $1
#if a file or a directory contains a space, i replace it with a "/", so i can scan the elements of lista without modify the default IFS 
    local lista=`ls|tr " " "/"`
    local array=()

    for elem in $lista
    do
#i replace "/" with space
        local temp=`echo $elem|tr "/" " "`
        if [ -d "$temp" ]
        then
            array+=("$1""/""$temp")
        elif [ -x "$temp" ]
        then
            echo "Executable file: ""$1""/""$temp"
        elif [ -e "$temp" ]
        then
            echo "Regular file: ""$1""/""$temp"
        fi
    done 

    for((i=0; $i<${#array[@]}; i++))
    do
        echo "Directory: ""${array[$i]}"
    done
    echo -----------
    #if array isn't empty, if there are subdirectories
    if [ ${#array[@]} != 0 ]
    then
        for((i=0; $i<${#array[@]}; i++))
        do
            entra_in_dir "${array[$i]}"
        done
    fi
}

entra_in_dir "$1"

和onChange函数

               <div className="col-md-12">
                    <div className="form-group clearfix">
                      <label htmlFor="" className="col-md-2 control-label">Authentication</label>
                      <div className="col-md-8">

                        <input type="radio"  name="authentication" value="No Authentication" onChange={this.Authentication.bind(this)} />
                        No Authentication


                      <input type="radio"  name="authentication" value="Master Credentials" onChange={this.Authentication.bind(this)} />
                      Master Credentials


                      </div>
                    </div>
                  </div>

onChange仅在我第二次单击时第一次被调用，onChange没有被调用无法识别出问题所在。

添加checked个道具，如下所示：

<div className="col-md-12">
  <div className="form-group clearfix">
    <label htmlFor="" className="col-md-2 control-label">
      Authentication
    </label>
    <div className="col-md-8">
      <input
        type="radio"
        name="authentication"
        value="No Authentication"
        checked={this.state.authentication === "No Authentication"}
        onChange={this.Authentication.bind(this)}
      />
      No Authentication
      <input
        type="radio"
        name="authentication"
        value="Master Credentials"
        onChange={this.Authentication.bind(this)}
        checked={this.state.authentication === "Master Credentials"}
      />
      Master Credentials
    </div>
  </div>
</div>;
