Question

并且提前感谢您对此进行调查，我试图在html（li）标签中显示2个数组的元素。这应该是回声的格式：

array1; array2
c201;100
c202;0
c450;320
......

将被推入数组的元素来自输入字段。我已经创建了以下代码，我可以看到正确的格式，但是当我复制并粘贴上面的值时，它会丢失格式而不是有两列，它会将array2的元素粘贴到array1的元素下面：

    <script>
    var array_accounts = [];
    var array_credits = [];
    var x = 0;
    var i = 0;
    var z = 0;
    function spara(){
    	var accounts_code_str = document.getElementById('accounts').value;
    	var accounts_code_comma = accounts_code_str.split(' ');
    	var accounts_code_comma = accounts_code_comma.join(';<br>');
    	array_accounts.push(accounts_code_comma);
    	console.log(array_accounts);
    	var iz_credits_str = document.getElementById('credits').value;
    	var iz_credits_comma = iz_credits_str.split(" ");
    	//var iz_credits_comma = iz_credits_comma.join('<br> ');
    	for(var z=0; z<iz_credits_comma.length; z++){
    		if(iz_credits_comma[z] < 0){
    			iz_credits_comma[z] = 0;
    		}
    	}
    	var iz_credits_comma = iz_credits_comma.join('<br> ');
    	array_credits.push(iz_credits_comma);
    	showAccounts();
    	showCredits();

希望这有帮助！

<script>
    var array_accounts = [];
    var array_credits = [];
    var x = 0;
    var i = 0;
    var z = 0;
    function spara(){
        var accounts_code_str = document.getElementById('accounts').value;
        array_accounts = accounts_code_str.split(' ');
        console.log(array_accounts);
        var iz_credits_str = document.getElementById('credits').value;
        var iz_credits_comma = iz_credits_str.split(" ");
        array_credits=iz_credits_comma;
        //var iz_credits_comma = iz_credits_comma.join('<br> ');
        for(var z=0; z<iz_credits_comma.length; z++){
            if(iz_credits_comma[z] < 0){
                iz_credits_comma[z] = 0;
            }
        }
        showAccounts();
    }
    function showAccounts(){

        var ol = document.createElement("OL");
        for (var x=0;x<array_accounts.length;x++){
            var li = document.createElement("LI");
            var textnode = document.createTextNode(array_accounts[x]+';'+array_credits[x]);
            li.appendChild(textnode);
            ol.appendChild(li)
        }
        document.getElementById("codes").appendChild(ol);
    }
</script>

修改两个javascript函数，这应该可以解决！感谢。
