Question

有人可以帮助我完成这项工作：

我有一个非重复数组的复选框。如果选中复选框以删除重复项，则它可以正常工作，但如果我取消选中remove duplicates，则复选框仍会删除重复项。

我想让它以如下方式工作：如果未选中（删除重复项）复选框，则在不删除重复项的情况下提取所有电子邮件。

感谢。

您只需几行...当您输出电子邮件时，您需要检查确定是否应使用所有电子邮件或唯一（不重复）电子邮件的字段：

<script type="text/javascript"> 
function findEmail() {
    var email = "No email address detected"; 
    var a = 0; 
    var ingroup = 0; 
    var separator = document.extractor.sep.value; 
    var groupby = Math.round(document.extractor.groupby.value);
    var outputEmails = [];

    if (separator == "new") separator = "\n"; 
    if (separator == "other") separator = document.extractor.othersep.value; 
    //match the email pattern in large text pasted in textarea. 
    var rawemail = document.extractor.rawdata.value.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);

    var norepeat = new Array(); 
    if (rawemail) {
        for (var i=0; i<rawemail.length; i++) {
            var repeat = 0; 

            // Check for repeated emails routine 
            for (var j=i+1; j<rawemail.length; j++) {
                if (rawemail[i] == rawemail[j]) {
                    repeat++;
                }
            } 

            // Create new array for non-repeated emails 
            if (repeat == 0) { 
                norepeat[a] = rawemail[i]; 
                a++; 
            } 
        } 

        // For output, use all or unique (non-repeated) emails?
        outputEmails = document.extractor["non-repeated"].checked ? norepeat : rawemail;
        if( document.extractor["sortbox"].checked ) {
            outputEmails = outputEmails.sort();
        }
        email = ""; 
        // Join emails together with separator 
        for (var k = 0; k < outputEmails.length; k++) {
            if (ingroup != 0) email += separator; 
            email += outputEmails[k]; 
            ingroup++; 

            // Group emails if a number is specified in form. Each group will be separate by new line. 
            if (groupby) {
                if (ingroup == groupby) { 
                    email += '\n\n'; 
                    ingroup = 0; 
                } 
            } 
        }
    }

    // Return array length 
    var count = norepeat.length; 

    // Print results 
    document.extractor.count.value = count; 
    document.extractor.rawdata.value = email; 
} 
</script>
