Question

我正在使用jquery v1.11.3，并且在尝试评估因元字符而被转义的选择器时出错：

未捕获错误：语法错误，无法识别的表达式：#foo \\ / bar \\。buzz

但是，如果我立即尝试在控制台中对其进行评估，那就可以了：

$('#foo\\/bar\\.buzz')
[<li id="foo/bar.buzz" >…</li>]

我的简单问题是为什么选择器不能在eval时工作但在控制台中工作？

您的代码正常运行。问题必须在其他地方。

searchedititext.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(final CharSequence arg0, int arg1, int arg2, int arg3) {
        // TODO Auto-generated method stub

        if (arg0.toString().length() > 1 ||!arg0.toString().isEmpty()) {
            dataAdapter.getFilter().filter(arg0.toString());
        }

    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        // TODO Auto-generated method stub
        // cancel.setVisibility(View.INVISIBLE);
    }

    @Override
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub
        // cancel.setVisibility(View.INVISIBLE);

        if (searchedititext.getText().toString().trim().length() > 1) {
            cancel.setVisibility(View.VISIBLE);
            listView.setVisibility(View.VISIBLE);
            gif1.setVisibility(View.INVISIBLE);
            setarrybg.setVisibility(View.VISIBLE);
        } else {
            //new SendsearchAsyncTaskbefore().execute();
            gif1.setVisibility(View.VISIBLE);
            listView.setVisibility(View.INVISIBLE);
            cancel.setVisibility(View.GONE);
            setarrybg.setVisibility(View.GONE);
            callflipanimation();
            searchresult.setText("");
        }
       // Toast.makeText(getActivity(),"vvvvvvv"+"\n"+arg0+"\n",Toast.LENGTH_LONG).show();
    }
});

$(function(){
  snippet.log('Yahooooooo: ' + $('#foo\\/bar\\.buzz').text())
});
