我正在尝试对表单中的一个字段执行验证

只有当该字段的值存在时,我才能调用API,否则将抛出错误消息

我尝试了SweetAlert2网站上的各种例子。我只想验证其中一个字段

Swal.fire({
        title: 'Are you sure you want to Save the Notes?',
        type: 'info',
        showCancelButton: true,
        confirmButtonColor: '#3085d6',
        cancelButtonColor: '#d33',
        confirmButtonText: 'Yes'
      }).then((result) => {

      console.log('result.value',result.value);
        if (result.value) {
          Swal.fire( {
            title: 'Download Notes',
              html:"<div class='b'><p>ID</p></div><input id='swal-input2' class='swal2-input' required/><div class='b'><p>Notes</p></div><input id='swal-input1' class='swal2-input' autofocus minlength='500' >",
            confirmButtonText: 'Save',
            preConfirm: (login) => {
              console.log('document.getElementById(swal-input2).value',document.getElementById('swal-input2').value);
              request_string = {
        "Request":

              "Col1": document.getElementById('swal-input1').value,

            }
          ]
      };
             fetch('API_URL', {
        headers: {

          'Content-Type': 'application/json',

        },
        method: 'POST',
        body: JSON.stringify(request_string)
      }
      ).then(response => {
        if (response.status !== 200) {

          return;
        }
        response.text().then(data => {

          response_data = data;
          response_jsonObj = JSON.parse(response_data);

        });
      }).catch(error => this.setState({ error }));
  },
  allowOutsideClick: () => !Swal.isLoading()

            }).then((result) => {
              swal({
              title: " Your  request is being processed!",
              icon: "success",
              confirmButtonText: 'OK'
            }).then((okay) => {
              if (okay) {
                history.push('/page1');
                history.push('/page2');
              }
            });
            });
        }
      })
Swal.fire({
标题:“是否确实要保存笔记?”,
键入:“info”,
showCancelButton:true,
confirmButtonColor:“#3085d6”,
cancelButtonColor:“#d33”,
confirmButtonText:“是”
})。然后((结果)=>{
console.log('result.value',result.value);
if(result.value){
游泳池火灾({
标题:“下载笔记”,

注释”, confirmButtonText:“保存”, 预确认:(登录)=>{ console.log('document.getElementById(swal-input2).value',document.getElementById('swal-input2').value); 请求\u字符串={ “请求”: [ { “Col1”:“value1”, “Col1”:“value2”, “Col1”:document.getElementById('swal-input2')。值, “Col1”:document.getElementById('swal-input1')。值, } ] }; 获取('API_URL'{ 标题:{ “Accept”:“application/json,text/plain,application/xml,*/*”, “内容类型”:“应用程序/json”, “访问控制允许标头”:“内容类型”, }, 方法:“POST”, 正文:JSON.stringify(请求字符串) } )。然后(响应=>{ 如果(response.status!==200){ 返回; } response.text().then(数据=>{ 响应数据=数据; response_jsonObj=JSON.parse(response_数据); }); }).catch(error=>this.setState({error})); }, allowOutsideClick:()=>!Swal.isLoading() })。然后((结果)=>{ 游泳({ 标题:“正在处理您的请求!”, 图标:“成功”, confirmButtonText:“确定” }).然后((好)=>{ 如果(好的){ history.push('/page1'); history.push('/page2'); } }); }); } })
如果您只想确保第一个输入(即
swal-input2
)不为空,则只需添加
预确认
,如下所示:

    preConfirm: () => {
      if (document.getElementById('swal-input2').value) {
         // Handle return value 
      } else {
        Swal.showValidationMessage('First input missing')   
      }
    }

您可以找到工作解决方案

嗨,各位,这是修复后的代码示例:
