如何将剃刀视图模态属性值传递给javascript函数

Question

我尝试将razor值发送给jquery funcion.

视图:

@Html.TextBoxFor(model => model.NumTransportado, new { @class = "form-control input-sm", id = "NumTransResp" + Model.ServicosID + "", name = "NumTransResp" + Model.ServicosID + "", onchange = "PreencheDadosVendedor(this, 3, " + @Model.ServicosID + ")" })

我可以使用除以外的所有参数 " + @Model.ServicosID + "

Js文件:

function PreencheDadosVendedor(idVend, tipoFuncionario, idServicoEdicao) {
$.getJSON("/Contrato/getDadosVendedor", { id: $(idVend).val(), tipoFuncionario: tipoFuncionario },
  function (result) {
      switch (tipoFuncionario) {
          case 1:
              $("#NomeVendedor_Contrato").val(result.NomeVendedor);
          case 2:
              $("#NomeTransResponsavel").val(result.NomeVendedor);
          case 3:
              $("#NomeTransResponsavel_" + idServicoEdicao + "").val(result.NomeVendedor);
      }
  });
}

我尝试做的idSericoEdicao是我的@Model.ServicosID,但我有相同的结果:unifined

您未定义的原因(假设值是一个字符串)是因为您需要将其包装@Model.ServicosID在引号中,否则它将查找属性的值作为变量的名称,而只需要将值作为一个字符串.

试试这个:-

@Html.TextBoxFor(model => model.NumTransportado, 
                  new { @class = "form-control input-sm", 
                    id = "NumTransResp" + Model.ServicosID + "", 
                    name = "NumTransResp" + Model.ServicosID + "", 
                    onchange = "PreencheDadosVendedor(this, 3, '" + @Model.ServicosID + "')" });
                                                               ^____                     ^____                                  

或者更好地做到这一点,而不是添加onchange属性; 附加一个事件,并使用data-*属性来存储元素特定的值,这样你就可以分离出html和js:

即:

@Html.TextBoxFor(model => model.NumTransportado, 
                      new { @class = "form-control input-sm myclass", //Add a class  
                        id = "NumTransResp" + Model.ServicosID + "",
                        data_tipoFuncionario = 3, //Add a data attribute 
                        name = "NumTransResp" + Model.ServicosID + ""});

和

$('.myclass').change(function(e){
     var idServicoEdicao = this.id.replace("NumTransResp",""),  //get the part from its own id
         tipoFuncionario = $(this).data("tipoFuncionario"); //get the value from data attribute

     $.getJSON("/Contrato/getDadosVendedor", { id: this.value, tipoFuncionario: tipoFuncionario },
 function (result) {
      switch (tipoFuncionario) {
          case 1:
              $("#NomeVendedor_Contrato").val(result.NomeVendedor);
          case 2:
              $("#NomeTransResponsavel").val(result.NomeVendedor);
          case 3:
              $("#NomeTransResponsavel_" + idServicoEdicao).val(result.NomeVendedor);
      }
  });

});
