Javascript中拼接大量字符串的方法

复制代码 代码如下:

$sql=<<<EOD
select *
from pages
where pagename='$pn'
EOD;

复制代码 代码如下:

print """
This is an example of a string in the heredoc syntax.
This text can span multiple lines
"""

复制代码 代码如下:

var str = "\
Here is line one \
And line two \
Finally, line three! \
";

alert(str);

复制代码 代码如下:

     var __template =
            '<tr>'+
                '<td>#salarySN#</td>'+
                '<td>#name#</td>'+
                '<td>#TDR_NAME#</td>'+
                '<td>#TSD_NAME#</td>'+
                '<td>#WORK_STATUS#</td>'+
                '<td>#isleader_display#</td>'+
                '<td>'
                    +'<a href="javascript:void(-1)">设置角色</a>'
            +'</td></tr>';

复制代码 代码如下:

function aHereDoc() {/*
Hello, World!
I am a JavaScript here document.
Use the 'hereDoc' function to extract me.
*/}

function hereDoc(func) {
return func.toString().split(/\n/).slice(1, -1).join('\n');
}
console.log(hereDoc(aHereDoc));
