android - api >=19 的 mathjax

Question

mathml 的 mathjax 在所有具有 api<19 的手机中都像一个魅力，但我有一个平板电脑，我在 webview 中重新加载数据时遇到问题，即它第一次加载 mathml 但是当我重新加载另一个 mathml 代码时相同的 webview 内容没有改变......代码是

wq.getSettings().setJavaScriptEnabled(true);
        wq.getSettings().setBuiltInZoomControls(true);
        wq.getSettings().setLoadWithOverviewMode(true);
        wq.loadDataWithBaseURL("http://bar", "<script type='text/x-mathjax-config'>"
                +"MathJax.Hub.Config({ "
                +"showMathMenu: false, "
                +"jax: ['input/MathML','output/HTML-CSS'], " // output/SVG
                +"extensions: ['mml2jax.js'], "
                +"TeX: { extensions: ['noErrors.js','noUndefined.js'] }, "
                //+"'SVG' : { blacker: 30, "
                // +"styles: { path: { 'shape-rendering': 'crispEdges' } } } "
                +"});</script>"
                +"<script type='text/javascript' "
                +"src='file:///android_asset/MathJax/MathJax.js'"
                +"></script><span id='text'> </span> <span id='math'></span>", "text/html", "utf-8", "");
if (android.os.Build.VERSION.SDK_INT < 19)
        {
            wq.loadUrl("javascript:document.getElementById('math').innerHTML='"
                + "<math xmlns=\"http://www.w3.org/1998/Math/MathML\">"
                + "<mstyle displaystyle=\"true\">"
                + doubleEscapeTeX(questn)
                + "</mstyle></math>';");
            wq.loadUrl("javascript:MathJax.Hub.Queue(['Typeset',MathJax.Hub]);");
        }
        else
        {
            wq.loadUrl("javascript:document.getElementById('math').innerHTML='"
                    + "<math xmlns=\"http://www.w3.org/1998/Math/MathML\">"
                    + "<mstyle displaystyle=\"true\">"
                    + doubleEscapeTeX(questn)
                    + "</mstyle></math>';");              wq.evaluateJavascript("javascript:MathJax.Hub.Queue(['Typeset',MathJax.Hub]);",null);
        }

请帮忙。提前致谢
