错误 javascript 函数

Question

您好，我正在使用 Dreamweaver，它在第 78 行检测到此 javascript 函数的错误。我无法发现问题。帮帮我。

function FrontPage_Form1_Validator(theForm)
 {
   var checkOK = "0123456789-.,";
   var checkStr = theForm.theField.value;
   var allValid = true;
   var validGroups = true;
   var decPoints = 0;
   var allNum = "";
   for (i = 0;  i < checkStr.length;  i++)
{
  ch = checkStr.charAt(i);
  for (j = 0;  j < checkOK.length;  j++)
  if (ch = = checkOK.charAt(j))                 //------This is line 78------//
    break;                              
  if (j = = checkOK.length)
{
  allValid = false;
  break;
}
  if (ch = = ".")
{
  ....
   //will cut code here since it's not letting me post with so much code.

你的等号之间有一个space。

将 = = 更改为 ==。
