Javascript: is a pseudo protocol. Other pseudo protocols include mail: & nbsp; Tel: & nbsp; file: & nbsp; and so on
≪ a & nbsp; id = & quot; jspswedit & quot; & nbsp; class = & quot; set item & amp; quot; & nbsp; javascript:; & quot; & gt; change password & lt; a & gt;
Javascript: means to execute a JavaScript code when the & lt; a & gt; default action is triggered, while & nbsp; javascript:; means to execute nothing, so there is no response when you click & lt; a & gt
In this case, an event callback is bound to & lt; a & gt; to perform business, such as:
document.getElementById (&# 39; jspswedit & # 39;). Addeventlistener (&# 39; click & # 39;, & nbsp; function (E) & nbsp; {& nbsp; & nbsp; e.preventdefault(); & nbsp; & nbsp; / / when & lt; a & gt; trigger click, process business}, & nbsp; false);
