我使用名为js-graph-it
的连接器框架来连接我网页上的元素。当我运行一个html文件作为该项目的工作演示时,它工作正常,但当我将其包含在项目中时,连接线丢失了。
这是代码
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="js-graph-it.js"></script>
<link rel="stylesheet" type="text/css" href="js-graph-it.css">
<style>
.canvas {
font-family: tahoma;
}
.block {
position: absolute;
border: 1px solid #7DAB76;
background-color: #BAFFB0;
padding: 3px;
}
/*.connector {
background-color: #FF9900;
}*/
.source-label, .middle-label, .destination-label {
padding: 5px;
}
</style>
</head>
<body onload="initPageObjects();">
<div class="canvas"
style="width: 1350px; height: 1250px;">
<h1 class="block" id="h1_block"
style="left: 100px; top:10px;">
h1 block
</h1>
<h2 class="block" id="h2_block"
style="left: 800px; top: 100px;">
h2 block
</h2>
<h3 class="block" id="h3_block"
style="left: 100px; top: 180px;">
h3 block
</h3>
<h2 class="block" id="h4_block"
style="left: 100px; top: 480px;">
h2_new block
</h2>
<!-- <div class="connector h1_block h2_block"></div>
<img src="arrow.gif" class="connector-start">
<img src="arrow.gif" class="connector-end">
<label class="source-label">start</label>
<label class="middle-label">middle</label>
<label class="destination-label">end</label>
</div> -->
<div class="connector h1_block h2_block">
<!-- <img class="connector-end" src="arrow.gif"> -->
</div>
<div class="connector h2_block h3_block">
<!-- <img class="connector-end" src="arrow.gif"> -->
</div>
<div class="connector h2_block h4_block">
<!-- <img class="connector-end" src="arrow.gif"> -->
</div>
</body>
</html>
我还附上了屏幕截图,证明它是一个独立的文件。
答案 0 :(得分:1)
在JSFiddle中将onDomready
更改为No wrap - in <head>

基本上,对于那些“包装”选项,initPageObjects
函数不会位于需要从HTML内联事件处理程序调用的顶层。
更好的选择是在脚本中创建动态事件处理程序,例如:
window.addEventListener('load',initPageObjects);
