    <p>I'm new to JSP, I m trying to pass <code>javascript</code> value to <code>jsp</code> method.</p> <p>In the below loop I m fetching list from java class and looping through with the selected value from dropdown in jsp i.e. <code>yearVal</code> and which value is equal assigning to a java variable. Inside the <strong>for</strong> loop, its showing the correct value for the String variable but outside the <strong>for</strong> loop its showing the last value in the list. I need to get correct value so that I can pass that String variable to a method.</p> <pre><code>&lt;% String valYear=""; %&gt; &lt;%for(int k=0;k&lt;lists.getYearList().size();k++){%&gt; if(yearVal==&lt;%= lists.getYearList().get(k)%&gt;){ &lt;%valYear = lists.getYearList().get(k);%&gt; alert('inside scriptlet:::'+&lt;%=valYear%&gt;); } &lt;%}%&gt; alert('outside scriptlet year val:::'+&lt;%=valYear%&gt;); </code></pre> <p>In java the arraylist is as below:</p> <pre><code>public List&lt;String&gt; yearList = new ArrayList&lt;String&gt;(); public List&lt;String&gt; getYearList() { if(yearList.isEmpty()){ yearList.add("2012"); yearList.add("2013"); yearList.add("2014"); yearList.add("2015"); yearList.add("2018"); } return yearList; } public void setYearList(List&lt;String&gt; yearList) { this.yearList = yearList; } </code></pre> <p>The last value 2018 is assigned to java variable in jsp instead of assigning the variable whicvh is equal in if loop.</p> <p>Im trying like below:</p> <p>For ex:</p> <pre><code>if(month != '11'){ alert('if::'+month); &lt;%abc = true;%&gt; }else{ alert('else::'+month); &lt;%abc = false;%&gt; } </code></pre> <p>Though it is going inside if condition, its not setting abc to <code>true</code>, its setting abc to <code>false</code>.</p>

    1. COIt seems the problem with the scope of the variable. Can you please post the full jsp code because we can not see the declaration of the few variable so that we can validate with it's scope.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
