url - how to get textbox value and put it in the URL?

Question

I'm using javascript for my codes: I have this sample screenshot of my website, my problem is I don't know how to get the value (coordinates) of the text box and put it in the URL. I tried this code ' window. location = window.location + '?loc=' + document.getElementById("latlng").value; " and its adding the value in the URL but it keeps on refreshing/loading my page, what seems to be the problem? please help me. than you!

設定window.locationすると、ページが強制的にリロードされます。

ページ全体をリロードせずに地図上のピンの位置を変更するには、Google Maps APIを使用する必要があります。
