Javascript 调整边界以缩放以包括所有标记

传单地图的JavaScript在下面，靠近底部，您将看到我的fitBounds定义

问题是我不知道如何准确地使用它，或者在代码中把它放在哪里使它工作，即缩放以包括所有标记，而不是硬编码坐标

看来我没有试过什么能让它正常工作

VarMap=L.map'map'.setView[39.202903，-94.602907]，20； L.tileLayer'https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png？access_token=pk.eyj1ijoibwwwwym94iiwiysi6imnpejy4nxvycta2emycxbdhrqcmz3n3gifq.rjfig214ariislb6b5aw'{ maxZoom:18， 属性：“映射数据©；贡献者”+ ', ' + “图像”， id:“地图盒。街道” }.addTomap； 函数onLocationFounde{ var半径=e.精度/2； L.circlee.latlng，radius.addTomap； marker1=L.marker[39.199178，-94.643435].addTomap； marker1.BindPopup1050KC0，修改人：A39.199178，-94.643435EM29qe.openPopup； marker2=L.marker[39.2859182，-94.667236].addTomap； marker2.bindPopup2007KD0YEXKaren McmackinPlatte Co.，修改人：A39.2859182，-94.667236EM29pg98.openPopup； marker3=L.marker[39.233982，-94.666035].addTomap； marker3.bindPopup3048N0RLDavid CopelandClay Co.，MODist:A39.233982，-94.666035EM29ri.openPopup； marker4=L.marker[39.33353，-94.76145].addTomap； marker4.bindPopup4052W0JSHJohn HeavenerPlatte Co.，修改人：A39.33353，-94.76145EM29oi.openPopup； } 函数onLocationError{ 警报e.message； } 地图。在'locationfound'，onLocationFound； 在'locationerror'上的映射，onLocationError； map.fitbunds[ [39.199178, -94.643435], [39.2859182, -94.667236], [39.233982, -94.666035], [39.33353, -94.76145], ]; 定位{ setView：对， 最大缩放：10， };

你的最后一次尝试就快到了。既然您已经在维护一个L.marker数组，我建议使用我将其设置为全局的L.featureGroup，并使用featureGroup上的getBounds设置地图的边界。你可以根据你对全球化的厌恶程度进行调整

var map = null;
var zoomLevel = 20;
var markers = [];

// starting point for the map and a zoom level of 20
var map = L.map('map').setView([39.202903, -94.602907], zoomLevel);

L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw', {

如果需要设置的边界是常量，那么在初始化映射时，您可以在setView调用的位置设置它们一次。你可能只需要一个或另一个，而不是两个。@Peeebe，谢谢你这么做，但我不明白怎么做的语法。你能给我举个例子吗？我开始写答案，但后来注意到你对fitBounds有错误的想法-它需要一个只有两个元素的LatLngBounds-矩形的对角。我想你是想用它画一个不规则的形状，这是行不通的。@peeebee恐怕我还是不懂语法。好的。你能用英语解释一下你想达到什么目的吗？我看到你做了一些小改动，使标记成为全局标记，并将它们应用到map3.php中，但它仍然没有缩放以显示所有标记。你对我对全球人的厌恶程度的评论也引起了我的兴趣。我不确定这是什么意思。看起来问题出在下面的错误；传单.js:5未捕获错误：边界无效。在e.fitBounds.js:5在map1.php？NetID=888:183不要忘记Peeebee；我在理解语法方面进展不大。传单页面提供了您可以做的所有事情，但没有语法示例。用足够的代码制作一个JSFIDLE来演示这个问题，我将与您一起解决。
