In general, it s best to let html handle the text, and jqMath handle the math. For example, write " using $y = (x+1)/(x+2)$", or "<td>$x+y = 2$<td>(1)" inside an html table.
You have to be able to separate user input into mathematics and non-mathematics. If a user inputs "using y=x" you don t want "using" parsed as the product of 5 variables u, s, i, n, and g. Similarly, if he inputs extra spaces that you want to keep outside the mathematics, you have to capture them using regular expressions or something, and don t pass them to jqMath. If you want the spaces to be part of the mathematics, you could make the user input able or sp or ext or something, though most users won t know to do that. You could tell users that they need to put $ $ around their mathematics if they want it to format, and then you could search for that.
Basically, jqMath isn t smart enough to tell what s math and what isn t, without $ $ to help.
Probably 0.2.0 will be out in a couple months, or at least I ll have a version I could send you by then.
<>Update>: 新版本支持/文本和/或html
使用批次和“”在公式内留出空间
HTML source : [ ext"average speed" = ext"distance traveled" / ext"elapsed time"]

It doesn t look like it can be done. To quote the page you provided:
