几個js

1,在用戶端計算

function calculate()
    {
       var obj = document.mod_form_det;
       var list_pr,price,disc_pct,disc;
      
       disc = parseFloat(obj.TextBox7.value);
       list_pr = parseFloat(obj.TextBox6.value);
      
       //若沒有折扣,則單價=報價價格;否則乘上折扣數
       if (disc==0)
       {        
         obj.TextBox8.value = list_pr;
         obj.TextBox10.value = list_pr;
       }
       else
       {
         disc_pct = disc/100;      
         price = parseFloat(list_pr*(1-disc_pct));
        // price = format_int(price);
         obj.TextBox8.value = price;                   
         obj.TextBox10.value = price;
       }
                 
       document.mod_form_det.TextBox8.focus();                                
    }

2,打開新窗口

function query_spec()
{
 var qod_part = document.mod_form_det.tbPart.value;
 window.open("query_spec.aspx?qod_part="+qod_part,"query_spec","menubar=no,scrollbars=yes,width=720");
 }

3,格式化數值

    //格式化數值,取到小位數第4位
    function format_int(g)
    {
       var f_int,point;
       f_int = g;            
       f_int = f_int.toString()
       point = f_int.indexOf(".");
       point = point+5;
       f_int = f_int.substring(0,point);  
       return f_int;
    }

4,讀取頁面中的元素

   function count_freight()
     {
       var str = document.mod_form_det;
       var terms;
       var freight,fob,cif,c_f,price,cont_qty;
      
       terms = str.qo_terms.value;             
       price = parseFloat(str.TextBox8.value);     
       freight = parseFloat(str.TextBox10.value);
       cont_qty = parseInt(str.TextBox11.value);
                       
       switch(terms)
       {
         
          case "0":
              str.TextBox12.value = "";
              break;
          case "1":  //FOB           
              str.TextBox12.value = price;             
              break;
          case "2":  //CIF = FOB+(貨櫃運費/裝櫃數量)+保險(0.5%)         
              cif = price+(freight/cont_qty)+((price + freight)*(5/1000));             
              cif = format_int(cif);
              alert(price + "+("+freight+"/"+cont_qty +")+(("+price+"+"+freight+")*("+5/1000+"))="+cif);
              str.TextBox12.value = cif;             
              break;
          case "3":  //C&F = FOB + (貨櫃運費/裝櫃數量)
              c_f = price + (freight/cont_qty);
              c_f = format_int(c_f);   
              alert(price + "+(" + freight + "/" + cont_qty + ")=" + c_f);
              str.TextBox12.value = c_f;             
              break;               
       }
     }

5,讀取多選框

function enter_ok()
{
        var obj,str,t_func,i;
        obj = "";
        str = document.form1;
                       
        for (i=0;i        {
           if(str.elements[i].checked)
           {         
             if(obj != "")
             {                   
                obj = obj + ";" + str.elements[i].value;
             }
             else
             {
                obj = obj + str.elements[i].value;
             }  
           }                       
        }       
        opener.document.mod_form_det.TextBox4.value=obj;
        opener.document.mod_form_det.TextBox5.focus();
        self.close();   

}

6,驗証輸入框的正確性

 

7,一進入畫面停留在第一個欄位

   function window_onload()
     {
      form1.e_part.focus();
      init();
     }

8,隱藏框架
