我有这个脚本（修改后的devbridge自动完成脚本）工作正常，但它有一个看起来非常难看的可笑长代码，我不是一个专业的程序员所以请耐心等待我，我希望不知何故我可以使用数组缩短它，但我不知道如何实现我甚至不确定数组是否是解决方案大声笑。在我的脚本中，我从2个变量中获取2个值，为分支名称后跟一个数字分配$ msB变量，为分支电话号码分配$ msT，当然其后跟一个数字。因此，如果它的branch1应该是$ msB1和$ msT1and。这是我的代码：

$('#autocomplete.autocomplete({
lookup: areas,
onSelect: function (suggestion) {
var thehtml = '<a href=\"tel:+63'+ suggestion.data +'\">' + suggestion.data + '</a><div>' + suggestion.value + ' branch found</div>';
$('#outputcontent.html(thehtml);
}
});
});
</script>
并输出上面的脚本这是代码
<div id="searchfield">
<form><input type="text" name="areas" class="biginput" id="autocomplete"></form>
</div>
<div>
<p id="outputcontent">
</p>
</div>
再次脚本工作我只是想找到一种方法，在变量之间的差异只是数字之后缩短脚本
我希望我已经解释得很好，我希望有人也可以帮助我：D
非常感谢

嗯，我可以想到一个可能的想法，虽然不是最安全的想法是使用函数将代码生成为字符串，然后对其进行评估（使用“eval”）。
第一部分的例子是：
function declareVars(varPrefix, varStart, varEnd, valuePrefix, valueStart){
var declaration = '', nextVar = '';
for (var i = varStart; i <= varEnd; i++){
nextVar = (varPrefix + i + ' = ' + valuePrefix + valueStart + ';\n');
valueStart ++;
declaration += nextVar;
}
return declaration;
}
var finalStatement =
declareVars('$msB', 1, 50, 'branch_name', 1) +
declareVars('$msT', 1, 50, 'branch_tel', 1);
console.log(finalStatement); //replace this with: eval(finalStatement)
但请记住，这种方法有很多注意事项，你可以在这里阅读更多内容：

但是，有一些方法可以保护自己免受“eval”的安全漏洞的影响 - 使用匿名函数来隐藏您的范围和其他内容。

您实际要问的是，您可以动态创建变量吗？ 幸运的是答案是肯定的。:)
一种可能的解决方案是使用＆＃34; eval＆＃34;，但它有很多缺点。 我建议，尝试更改代码结构，将所有变量保存为JSON对象中的键。动态创建对象键既简单又安全，并且简单如下：
allBranches = {
branch_name1: 'some data 1' ,
branch_name2: 'some data 2' ,
branch_name3: 'some data 3' ,
// etc...
}
var myData = {};
for (var i = 1; i < Object.keys(allBranches).length; i++){
myData['$msB' + i] = allBranches['branch_name' + i];
}
