javascript - 隐藏其他 div 时如何使 div 占用 100% 宽度

Question

这个想法是当第二个隐藏<图表>时，一个div占据屏幕<地图>的100％ 。另外我想知道为什么当我点击输入标签时它会密切执行该功能并且不等待按钮被点击。

function hidechart() {
  var x = document.getElementById("chart");
  if (x.style.display === "none") {
    x.style.display = "block";
  } 
  else {
    x.style.display = "none";
  }
};

* { padding: 0; margin: 0; }
html, body, #fullheight {
  min-height: 100% !important;
  height: 100%;
}
.leaflet-container { 
  position: fixed;
  width:  50%;
  height: 100%;
}
#chart{
  position:absolute;
  width: 50%; 
  height: 50px;
  top:2%;
  right:0;
}

<div id="map" ></div>
<div class="btn-group" style="position:fixed">
  <button onclick="hidechart()" >Graficas</button>
  <button type="button" id="alldep" class="btn" >Todos</button> 
</div>

<form id="form" onsubmit="return false;">
  <input style="position:fixed; top:0%; left:14%; width:10%;" type="text" onfocus="this.value=''" id="userInput" />
  <button style="position:fixed; top:0%; left:5%; width:8%;",stype="button" onclick="query();">Consultar</button>
</form>

<div id="chart"  align="right">
  <div class="row">
    <div id="chart-area"></div>
  </div>
</div>

这是您正在寻找的按钮功能吗？

var map = document.getElementById("map");
var chart = document.getElementById("chart");

function hideChart() {
  chart.classList.add("hide");
}

function query() {
  alert("query");
}

* { padding: 0; margin: 0; }
    html, body, #fullheight {
        min-height: 100% !important;
        height: 100%;
    }
.leaflet-container { 
    position: fixed;
    width: 100%;
    height: 100%;
    }
    
#map {
  position: absolute;
  z-index: 0;
  top: 0;
  bottom: 0;
  width: 100%;
}

#chart{
    position:absolute;
    text-align: center;
    height: 50%;
    left: 0;
    right: 0;
    bottom: 0;
    background-color: #efefef;
    right:0;
    width: 100%;
    z-index: 1;
    }
    
#chart.hide {
  opacity: 0;
  transition: opacity .5s ease-out;
}

.container {
  position: relative;
  width: 100%;
  height: 100%;
}

<div class="container">
  <div id="map" ></div>
   <div class="btn-group" style="position:fixed">
      <button onclick="hideChart()" >Graficas</button>
      <button type="button" id="alldep" class="btn" >Todos</button> 
  </div>

  <form id="form" onsubmit="return false;">
      <input type="text" onfocus="this.value=''" id="userInput" />
      <button type="button" onclick="query();">Consultar</button>
  </form>

  <div id="chart" align="right">
      <div class="row">
          <div id="chart-area">
            <h1>This is where the chart is</h1>
          </div>
      </div>
  </div>
</div>
