通过javascript获取两个字符串之间的String值

Question

我想从以下类型的字符串中获取 ";L0|" 和 ";GTSet" 之间的字符串值。

var test = "GP0|#9d72d96c-407f-4e45-b2e6-9361faf5808a;L0|#09d72d96c-407f-4e45-b2e6-9361faf5808a|Travel;GTSet|#ac96f075-b7d2-4e90-8dc2-da8875f395fc";
var test2 = "GP0|#15a06b93-f7aa-4dda-b0d6-7bf2d2905f27;L0|#015a06b93-f7aa-4dda-b0d6-7bf2d2905f27|Special Event;GTSet|#ac96f075-b7d2-4e90-8dc2-da8875f395fc";

这是我已经完成的。

var str = test2.match(";L0|" + "(.*?)" + ";GTSet");
 alert(str[1]);

和这个returns一个字符串，从最开始直到“;GTSet”

我猜您是从 SharePoint 搜索结果中获取此值的，对吗？如果是这样，根据 Automatically created managed properties in SharePoint Server 2013：

Data format for Managed Metadata.

To query for items tagged with a Managed Metadata field, you have to use the Unique Identifier for each label. You can find the Unique Identifier for each term in a term set in the Term Store Management Tool, on the GENERAL tab. In addition, the data format that is used in the query has to specify from which level in the term set the query should apply. This specification is set by adding one of the following prefixes to the Unique Identifier:

To query for all items that are tagged with a term: GP0|#

To query for all items that are tagged with a child of term: GPP|#

To query for all items that are tagged with a term from a term set: GTSet|#

基于此信息，以下示例演示了如何解析托管元数据的搜索结果值：

function parseTaxonomySearchResultValue(val){
    var taxValue = {TermSetGuids: [], TermValues: []};
    var parts = val.split(';');
    parts.forEach(function(part){
       if (part.startsWith("GP0|#")) //term?
       {
           var termGuid = part.replace("GP0|#", "");
           taxValue.TermValues.push({ TermGuid: termGuid});
       }
       else if (part.startsWith("GTSet|#")) //term set?
       {
            taxValue.TermSetGuids.push(part.replace("GTSet|#", ""));
       }
       else if (part.startsWith("L0|#")) //Term with label?
       {
            var termParts = part.replace("L0|#0", "").split('|');
            var termGuid = termParts[0];
            var termLabel = termParts[1];
            var result = taxValue.TermValues.filter(function(tv){  
                return tv.TermGuid == termGuid;
            });
            if (result.length == 0)
                taxValue.TermValues.push({TermGuid : termGuid, Label : termLabel});
            else
                result[0].Label = termLabel;
        }
    });
    return taxValue;
}


//Usage
var taxValue = 'GP0|#9d72d96c-407f-4e45-b2e6-9361faf5808a;L0|#09d72d96c-407f-4e45-b2e6-9361faf5808a|Travel;GTSet|#ac96f075-b7d2-4e90-8dc2-da8875f395fc';
var taxValue = parseTaxonomySearchResultValue(taxValue);
document.getElementById('output').innerHTML = "Term info:<br/>" + "Guid= " + taxValue.TermValues[0].TermGuid + "<br/> Label= " + taxValue.TermValues[0].Label;

<div id='output'/>
