    <p>my goal is to parse a string with an specific format to generate an javascript object structure out of it.</p> <p>one idea was to use the <a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/replace#Specifying_a_function_as_a_parameter" rel="nofollow">String.replace</a> with an function as parameter. so in the function you get all parts of the match. my test / example till now:</p> <p>the string:</p> <pre><code> !Norm: DIN 7985; M2: 2, 2, 2; M3:3,3; M10: 20,25; !Norm: DIN 7985 TX; M4: 4, 4 , 4; </code></pre> <p>my test code:</p> <pre><code>console.clear(); var sTmp = "!Norm: DIN 7985;\n M2: 2, 2, 2;\n M3:3,3;\n M10: 20,25;\n !Norm: DIN 7985 TX;\n M2: 6, 10 , 16;"; //console.log(sTmp); function replacer(match, p1, p2, p3, p4, offset, string){ //console.log("-"); console.log("match:", match); console.log("p1:", p1); console.log("p2:", p2); console.log("p3:", p3); console.log("p4:", p4); console.log("offset:", offset); console.log("string:", string); return "#"; } //(?=!Norm:\s?(.+);\s+) sTmp.replace(/\s*!Norm:\s?(.+);\s+(M\d+:.*\s*;)/g, replacer); </code></pre> <p>(tested in firebug) console log (shortend):</p> <pre><code>match: !Norm: DIN 7985; M2: 2, 2, 2; p1: DIN 7985 p2: M2: 2, 2, 2; p3: 0 p4: !Norm: DIN 7985; M2: 2, 2, 2; M3:3,3; M10: 20,25; .... offset: undefined string: undefined match: !Norm: DIN 7985 TX; M4: 4, 4 , 4; p1: DIN 7985 TX p2: M4: 4, 4 , 4; p3: 52 p4: !Norm: DIN 7985; M2: 2, 2, 2; M3:3,3; M10: 20,25; !Norm: DIN 7985 TX; M4: 4, 4 , 4; .... </code></pre> <p>so i can see that the idea works- it matches the norm and i get the Info in one substring. now there are the M3:... parts. so is there a option to specify that the part <code>(M\d+:.*\s*;)</code> matches up to the next !Norm: instead of the ; at the first occurrence? i think it should be possible with a lookahead or something?</p> <p>the goal behind this idea is to generate an javascript object like this out of the string:</p> <pre><code> oDataTmp = { DIN 7985 : { M2 : ["2", "2", "2"], M3 : ["3", "3"], M10 : ["20", "25"], } DIN 7985 TX : { M4 : ["4", "4", "4"], } } </code></pre> <p>i know you can do this by split and then parse line by line. i love the challenge to get this brain thing done and to understand how to do it :-)</p>

    1. COThe object you're getting doesn't seem to sync up with the string you had. Could you please include one that does?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
