bsr*_*bsr 14 javascript jquery
如何将Json字符串存储在隐藏的输入字段中.好吧,我可以通过编程方式完成它,但是转发出错了.由于我的字符串适度长,很难逃脱"所有名称的字符.请解释它是如何以编程方式工作(阶段1),因为控制台输出看起来相同.
[{"X":0,"Y":0,"W":0,"H":500},{"X":358,"Y":62,"W":200,"H":500}]test2.html:21
[{"X":0,"Y":0,"W":0,"H":500},{"X":358,"Y":62,"W":200,"H":500}]
test2.html:22

你可以这样做,但是非常糟糕,HTML:
<textarea id="jsondata" sytle="display:none"></textarea>
和JS
$(function(){
var myItems = [{"X":0,"Y":0,"W":0,"H":500}, {"X":358,"Y":62,"W":200,"H":500}]
$("#jsondata").val(JSON.stringify(myItems));
});
<input type="hidden" id="jsondata2" value="[{"X":0,"Y":0,"W":0,"H":500},{"X":358,"Y":62,"W":200,"H":500}]"/>
是不正确的.使用单引号'而不是"值字符串中的双引号来修复它(或转义")
<input type="hidden" id="jsondata2" value="[{'X':0,'Y':0,'W':0,'H':500},{'X':358,'Y':62,'W':200,'H':500}]"/>
