When you add a For loop statement for JavaScript in a SharePoint custom list page, the page will not open.

A custom new page for a normal list of SharePoint 2013, where I added a few lines of JavaScript code and the page won't open. ：

Really a word, Friendship Page said can not open ah. Then slowly compared to the discovery because there is a for loop in JavaScript, when the for loop is removed, the page can open normally, and when the for loop is added, the page will not open.

Reason: The list of custom pages is generally XSL format, for may be in the inside is a more special keyword, so it makes parsing difficult.

Workaround:

1. You can use the each method of jquery instead of a for loop

2. Add <! outside the For loop [cdata[...] > tags. Like <!. [Cdata[for (var i = 0; i <; i++) {//to Do}]]> this is escaped when parsing.
