Question

我正在从数据库中获取数据，并将数据在ASP.NET MVC视图页面中显示为表格格式。下面是Ajax调用。我将返回数据作为JSON字符串。我不知道为什么。对于所有视图页面，我都将其作为JSON对象。

尽管该值在JSON字符串中获取，但我尝试使用“ JSON.parse（jsonData）”转换为JSON对象。它在我的本地环境中运行良好。当我在舞台上部署代码时。生产线在Json Parse断裂。

为什么我遇到此错误。代码中有什么用吗？

JSON字符串：

void * funcao_somadora(void * es){

  int i;

  estrutura_geral * const estrutura = es;

  pthread_mutex_lock(estrutura->mutex);

  pthread_cond_signal(estrutura->cond);

  pthread_mutex_unlock(estrutura->mutex);

  for(i=0;i<barreira;++i){
  pthread_mutex_lock(estrutura->mutex);
    while(items_buffer == 0) {
            pthread_cond_wait(estrutura->consumir, estrutura->mutex);
  }

     soma_global+=buffer[items_buffer];
     items_buffer--;

     printf("A thread somadora: somou %d, existem %d elemnetos no buffer\n",buffer[items_buffer],items_buffer);

    if(items_buffer==0){
    sched_yield();
    //pthread_cond_signal(estrutura->produzir);

    }
    pthread_mutex_unlock(estrutura->mutex);    

}
  printf("A tarefa somadora está de saída\n");
  pthread_exit(NULL);

}

控制器方法：

$("#btnVendorSearch").click(function() {
if (RequiredFieldValidate() != false) {
    var SupplierNumber = $('#txtVendorNumber').val();
    $.ajax({
        type: "POST",
        url: getExactPath('/Supplier/GetSupDocuments'),
        async: false,
        data: {
            SupplierNo: SupplierNumber
        },
        dataType: 'Json',
        success: function(jsonData) {    
            var jsonobj = JSON.parse(jsonData);
            if (jsonobj.error == "" || jsonobj.error == undefined) {
                FillGrid(jsonobj);
            } else {
                console.log(jsonobj.error);
            }
        },
        error: function() {
            alert("Unable to fetch the data");
        }});}});

它应该返回如下。请帮助我。

public JsonResult GetSupDocuments(string SupplierNo) {
    string Error = "";
    DocumentumUtil dUtil = new DocumentumUtil();
    List < Attachment > AttachmentDetails = new List < Attachment > ();
    try {
    AttachmentDetails = dUtil.GetSupplierAttachments(SupplierNo);
    return this.Json(AttachmentDetails);
    } catch (System.Exception ex) {
        Error = ex.Message;
    }
    return this.Json(new {error = Error});
}

JSON字符串现在正在解析为数组对象。

jQuery.parseJSON()

jQuery Ajax调用返回的JSON字符串不作为对象数组
