如题,我想实现这样的效果:如果一条题录有DOI,则显示DOI;如果它没有DOI,则显示链接。例如:
AYALON Hanna, SHAVIT Yossi, 2004.Educational reforms and inequalities in Israel: The MMI hypothesisrevisited[J]. Sociology of education, 77(2): 103-120. DOI: 10.1177/003804070407700201. 上面这条文献有DOI,则只显示DOI,不显示链接。
DHALIWAL M. S., MITTAL A.,AGGARWAL A., et al, 2019. Determining the Factors Affecting the Selection ofPrivate Universities and Colleges in Indian Context: A Structural EquationModeling Approach[J]. Journal of Advanced Research in Dynamical and Control Systems,11(8): 2579-2590. https://www.researchgate.net/pub ... n_Modeling_Approach 上面这条文献没有DOI,则显示链接。
