这只是一个简单的例子而不是实际的事情.
仍然MutationObserver没有解雇,所以我对它是如何工作的假设是错误的.
$(function() {
var editButtonVisibility = function() {
console.log('bam');
}
$('#RiskPostcodeSummary span').on("change", function() {
console.log("pew pew");
});
var observer = new MutationObserver(function(e) {
editButtonVisibility();
});
observer.observe($('#RiskPostcodeSummary span')[0], {
characterData: true
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="RiskPostcodeSummary">
<span></span>
</div>
<input type="button" value="click" onClick="$('#RiskPostcodeSummary span').text('sdfsdf');" />MutationObserver当我更改文本时为什么不触发<span>？
