How to mask a datafield ?

ericchung

<p>for instance, <span style="font-size:14px;">a s</span><span style="font-size:14px;">tring "MyString" with mask covered as "M***ring", </span></p>
<p> </p>
<p>when setting a Format code @ in Custom Format String,</p>
<p>the result comes out as  "MySt***ring",</p>
<p>instead of covering, 3 asterisks was inserted into the string and the string length was <span style="font-size:14.3999996185303px;">extended</span><span style="font-size:14px;">.</span></p>
<p><span style="font-size:14px;">how to set a correct mask (format) to let</span><span style="font-size:14.3999996185303px;"> "MyString" become</span><span style="font-size:14.3999996185303px;"> "M***ring"?</span></p>
<p><span style="font-size:14.3999996185303px;">thanks.</span></p>

<p>In the data set binding you could use some script like this</p>
<pre class="_prettyXprint _lang-">
var field = new String();
var replacement = new String();

field = dataSetRow["CUSTOMERNAME"]
replacement = field.substring(0,3);
field = field.replace(replacement, "****");

field;
</pre>
