Javascript to clear form field on button click
提问by IRHM
I have a field called 'inputaddress' which a user types address details into, so they can perform a google map geocode.
我有一个名为“inputaddress”的字段，用户可以在其中输入地址详细信息，以便他们可以执行谷歌地图地理编码。
What I would like to do is when the user clicks on the 'searchfortheaddress' button, it will perform the geocode but will then clear the 'inputaddress' field.
我想做的是当用户单击“搜索地址”按钮时，它将执行地理编码，但随后会清除“输入地址”字段。
Could someone perhaps tell me please how I can clear the field.
有人可以告诉我如何清除该字段。

Would $('#inputaddress').html("");or document.getElementById('inputaddress').value=""work?
会$('#inputaddress').html("");或document.getElementById('inputaddress').value=""工作？

i am assuming that u id your input address field addrjust add this code to the onclickevent of your searchforaddressbutton
我假设您确定了您的输入地址字段，addr只需将此代码添加到onclick您的searchforaddress按钮事件中
document.getElementById('addr').value="";
like this (i am assuming is of ur searchforaddressbutton is searchforaddress)
像这样（我假设是你的searchforaddress按钮是searchforaddress）
document.getElementById('searchforaddress').onclick=function() {
document.getElementById('addr').value="";
};
