< html>
< head>
< / head>
< body>
< input name =txttype =textid =new
placeholder =请输入一些文字。>
< script type =text / javascriptsrc =autoComplt.js>< / script>
< script>
var words = [];
函数get_words（q，calbk）
{
var xmlhttp = new XMLHttpRequest（）;
var url =http://xxxx.poc.yyyyy.com/v1/xxx/suggest?authKey=baef7f8e39c53t6990f852c8a14b7f6018b58&q=
+ q +& rows = 8;
xmlhttp.onreadystatechange = function（）{
if（xmlhttp.readyState == 4&& xmlhttp.status == 200）{
var data = JSON.parse（xmlhttp.responseText）;
var items = data.suggestions;
var words = items.map（function（item）{return item.suggestion;}）;
console.log（文字）;
calbk（words）
}
}
xmlhttp.open（GET，url，true）;
xmlhttp.send（）;
}
var input = document.querySelector（input [name = txt]）;
autoComplt.enable（input，{
hintsFetcher：function（v，openList）{
console.log（in）
get_words（v，openList）
}
}）;
< / script>
< / body>
< / html>
如何从文本框中移除该HTML标记。
函数stripHTML（html）{
var div = document.createElement （ DIV）;
div.innerHTML = html;
返回div.textContent || div.innerText;
}

</html>
how can i remove that html tag from the textbox.
You can convert an HTML string to text by inserting it into a DOM element and then asking for just the text back out. This will work in even older versions of IE:
function stripHTML(html) {
var div = document.createElement("div");
div.innerHTML = html;
return div.textContent || div.innerText;
}
