For example:<\/p>\n<p>if <code>&lt;%=DataRet.get(2)%&gt;<\/code> returns a string <code>\"TEST\"<\/code> then the resulting JS would look like:<\/p>\n<pre><code>var id=TEST\n<\/code><\/pre>\n<p>And that would just simply break because there is no variable named TEST. You need to enclose it in double or single quotes like:<\/p>\n<pre><code>var id=\"&lt;%=DataRet.get(2)%&gt;\";\n<\/code><\/pre>\n<p>Also you have to keep in mind the semicolons at the end of every line, and escape any possible chars that can break the JS code. Remember, the JS code has not been executed yet after the JSP has compiled, so it is like if you wrote that JS code manually.<\/p>\n<p>If this code is not working start by checking what <code>&lt;%=DataRet.get(2)%&gt;<\/code> is returning, and also if there are any JS errors.<\/p>\n<p>Hope it helps.<\/p>\n<\/p><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\">1<\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved store value of my Java function return String In JavaScript variable [closed] <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] The storing of data from a JSP scriptlet should be pretty straight forward just like you have it. var id=&lt;%=ctx.getAttribute(&#8220;id&#8221;)%&gt; Although I would recommend you to be careful with the returning data, if it isn&#8217;t a number for sure, then you must put it between quotes just to be sure the JS doesn&#8217;t break. &#8230; <a title=\"[Solved] store value of my Java function return String In JavaScript variable [closed]\" class=\"read-more\" href=\"https:\/\/jassweb.com\/solved\/solved-store-value-of-my-java-function-return-string-in-javascript-variable-closed\/\" aria-label=\"More on [Solved] store value of my Java function return String In JavaScript variable [closed]\">Read more<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[320],"tags":[464,346,323,333],"class_list":["post-24097","post","type-post","status-publish","format-standard","hentry","category-solved","tag-css","tag-html","tag-java","tag-javascript"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>[Solved] store value of my Java function return String In JavaScript variable [closed] - JassWeb<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/jassweb.com\/solved\/solved-store-value-of-my-java-function-return-string-in-javascript-variable-closed\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"[Solved] store value of my Java function return String In JavaScript variable [closed] - JassWeb\" \/>\n<meta property=\"og:description\" content=\"[ad_1] The storing of data from a JSP scriptlet should be pretty straight forward just like you have it. var id=&lt;%=ctx.getAttribute(&quot;id&quot;)%&gt; Although I would recommend you to be careful with the returning data, if it isn&#8217;t a number for sure, then you must put it between quotes just to be sure the JS doesn&#8217;t break. ...
