trip_progress='<div><img src="red.png" onmouseover="myclick('+myJSONObject+')" /></div>';
var headID = document.getElementsByTagName("head")[0];

You could potentially use closures to call a function that will generate a dynamic function that you can then call, though i've never used this capability. 您可能会使用闭包来调用一个函数，该函数将生成一个可以随后调用的动态函数，尽管我从未使用过此功能。 You can find more info about closures here . 您可以在此处找到有关闭包的更多信息。 They are a feature of many functional programming languages. 它们是许多功能编程语言的功能。

Please check out my edit. 请检查我的修改。 If you JSON.stringify your object, then your code will work as you expect. 如果您对对象进行JSON.stringify ，则您的代码将按预期工作。
var gmarkers = {key: 'value'};
var ss = document.createElement('script');
var scr = "function caller(){ alert("+JSON.stringify(gmarkers)+") ;}"; //alert(scr); var tt1 = document.createTextNode(scr); ss1.appendChild(tt1); var hh1 = document.getElementsByTagName('head')[0]; hh1.appendChild(ss1); caller()
var tt = document.createTextNode(scr);
ss.appendChild(tt);
var hh = document.getElementsByTagName('head')[0];
hh.appendChild(ss);
caller();
