我正在尝试根据传入的字符串选择边。这是一个示例 json:
{
"group": "edges",
"data": {
"id": "8",
"source": "Q14814",
"target": "P20393",
"direction": "|->",
"Sources": {
"dataSource": "database",
"dbId": "0",
"sourceId": "1368140",
"sourceType": "REACTION"
}
}
每条边可能有一个源，或一个源数组。我想选择所有具有我传入的字符串的 sourceId 的边。因此，如果我传入一个字符串“1368140”，我想获取所有包含 sourceId 为“1368140”的源的边。
我尝试了几种不同的方法来选择它，包括:
cy.filter('edge[reactomeId = "' + string + '"]'));
或
cy.elements('edge[reactomeId = "' + string + '"]'));
或
cy.filter('reactomeId = ' + string + ''));
以及这方面的所有其他排列。有谁知道如何正确选择这些边？
最佳答案
这是我的做法:
// The syntax is important here!
cy.edges('[source = "' + string + '"]');
可以找到此特定语法的来源 here .
