Parameter “JsEncode” defines that the value of corresponding variable or result of function will be converted to the format accessible for Javascript-output. Managing characters for Javascript (like quotes, equal signs etc) will be escaped.

NOTE: By default the resulting content will be parsed (all <#..> tags will be evaluated) before to apply this filter. You can control this behavior throught the parameter AnalyzeTagParams

<#JavascriptVar setValue="var test = '1';">
<#JavascriptVar JsEncode="1">

Output:

var test = \u00271\u0027;
