Question

我有详细的功能，它给了我以下错误

未捕获的参考错误：分配中的左侧无效。

function obtenerValorPorColorSemaforo(sumCumplimiento, valueColorVerde, valueColorAmarillo) {
         var result = null;
         var porColorVerde = parseFloat(valueColorVerde); // Porcentaje Color Verde
         var porColorAmarillo = parseFloat(valueColorAmarillo); // Porcentaje Color Amarillo.

         if (parseFloat(sumCumplimiento) = 0.00) {
           // Color gris
           result = "panel-defaluft";
         }

         else if (parseFloat(sumCumplimiento) >= porColorVerde) {
           // Color VERDE
           result = "panel-success";
         }

        else if(parseFloat(sumCumplimiento) < porColorVerde &&
                parseFloat(sumCumplimiento) >= porColorAmarillo) {
           // Color AMARILLO
           result = "panel-warning";
         }

         else  {
           // Color ROJO
           result = "panel-danger";
         }

         return result;

       }

Answer 1

这是你的问题：

    if (parseFloat(sumCumplimiento) == 0.00) {
       // Color gris
       result = "panel-defaluft";
     }

它应该是：

Answer 2

你在if

中正在做什么

 if (parseFloat(sumCumplimiento) = 0.00) {
   // Color gris
   result = "panel-defaluft";
 }

可能你错过了额外的==
