Question

所以我有这个功能，当if语句完成时，它除了冻结页面之外什么都不做。

    function doGetWord(){



            word = F.gword.value;
            if (word == "") {
                $("input").hide();
                $("input.wordi").show();
                $("input.bi").show();
            }
            else{
                wLength = word.length;
                cs = ++cs % 2
                for(var i = 0; i < wLength; i++){
                    document.getElementById("dword").innerHTML += "_ "
                }
                $("input.wordi").hide()
                $("input.bi").hide()
                $("input.in2").show()
                $("input.bi2").show()
            }

        }

Answer 1

在评论中无法得到我想要的东西，所以我会尝试在这里看到我用doGetWord（）函数看到的一些明显问题。

F.gword.value未在函数中定义。如果它作为全局存在于其他位置，则放置console.log（F.gword.value）;在功能中使用它之前。
我无法判断F是否曾在任何地方定义过。尝试使用console.log（F）并查看它是否已定义。

在使用F.gword.value

       if(!F.gword.value)
         return;

这应该会停止代码中的异常。您需要在输入中填写名称，以便不要尝试使用未定义的值。

为undefined添加测试。

if（word ==“” || word == undefined ）{....

您可能已经知道这一点，但HTML中的doGuess（）未在您的代码中定义。

  <center>

是过时/非标准的。应该使用像

  <div class"center">

当if成为页面时，只会冻结js
