How can I append an integer to the link name?

Question

i have defined the following JavaScript:-

<script type="text/javascript">
var html = ' ';
var i = 1 ;

if ( "#variable.1#" != null) {
    html += '<div><a href="/Service1.svc/vf/img?imgid=#variable.1#" >"View Page" + i </a></div>';
i =i +1;
}

if ( "#variable.2#" != null) {
   html  += '<div><a href="/Service1.svc/vf/img?imgid=#variable.2#"> "View Page"  i </a></div>';
i = i=1;
}

if ( "#variable.3#" !=null) {
    html += '<div><a href="/Service1.svc/vf/img?imgid=#variable.3#" >"View Page" + i </a></div>';
i = i+1;
}


document.write(html);
</script>

but the output of the above javascript incase all the variables are not null will be:-

"View Page" + i
"View Page" i
"View Page" + i

so how i can force the output to be External Intigration Images

View Page 1
View Page 2
View Page 3

Answer 1

采用

html += '<div><a href="/Service1.svc/vf/img?imgid=#variable.3#" >View Page '+i+'</a></div>';

Answer 2

You need to format your strings as follows:

html += '<div><a href="/Service1.svc/vf/img?imgid=#variable.3#" >"View Page" ' + i + '</a></div>'

This will take the value of i and append it into the string, not i itself.

As an additional bit of information, keep in mind that in JavaScript when a string is added to an integer, the integer is parsed as a string rather than the inverse. As is noted in the comment,

var answer = 1 + 1 + "1"
// answer = 21, not "111" and not 3
