[-310, 1, 361, 379, 403, 424, 450, 486, 487, 491] ["preload(-310)", "continue(1)", "load(361)", "parse(379)", "head(403)", "content(424)", "css(450)", "script(486)", "renderd(487)", "defer(491)"]
If you have problems reading such as JavaScript and CSS, it is necessary to set the pjax of built-in load.reload and load.ignore parameter.
This plug-in is like a trial version. If you want to optimize and customize in more detail, it is recommended that you set directly jQuery plug-ins built without the use of this plug-in.
